+Too many issues will kill our team's development velocity, drastically.
+Make sure you have checked all steps below.
+
+### Prerequisite
+* [ ] Make sure your problem is not listed in [the common build problems](https://github.com/pyenv/pyenv/wiki/Common-build-problems).
+* [ ] Make sure no duplicated issue has already been reported in [the pyenv issues](https://github.com/pyenv/pyenv/issues). You should look for closed issues, too.
+* [ ] Make sure you are not asking us to help solving your specific issue.
+  * GitHub issues is opened mainly for development purposes. If you want to ask someone to help solving your problem, go to some community site like [Gitter](https://gitter.im/yyuu/pyenv), [StackOverflow](https://stackoverflow.com/questions/tagged/pyenv), etc.
+* [ ] Make sure your problem is not derived from packaging (e.g. [Homebrew](https://brew.sh)).
+  * Please refer to the package documentation for the installation issues, etc.
+* [ ] Make sure your problem is not derived from plugins.
+  * This repository is maintaining `pyenv` and the default `python-build` plugin only. Please refrain from reporting issues of other plugins here.
+
+### Description
+- [ ] Platform information (e.g. Ubuntu Linux 16.04):
+- [ ] OS architecture (e.g. amd64):
+- [ ] pyenv version:
+- [ ] Python version:
+- [ ] C Compiler information (e.g. gcc 7.3): 
+- [ ] Please attach the debug trace of the failing command as a gist:
+  * Run `env PYENV_DEBUG=1 <faulty command> 2>&1 | tee trace.log` and attach `trace.log`. E.g. if you have a problem with installing Python, run `env PYENV_DEBUG=1 pyenv install -v <version> 2>&1 | tee trace.log` (note the `-v` option to `pyenv install`).
+- [ ] If you have a problem with installing Python, please also attach `config.log` from the build directory
+  * The build directory is reported after the "BUILD FAILED" message and is usually under `/tmp`.
+- [ ] If the build succeeds but the problem is still with the build process (e.g. the resulting Python is missing a feature), please attach
+  * the debug trace from reinstalling the faulty version with `env PYENV_DEBUG=1 pyenv install -f -k -v <version> 2>&1 | tee trace.log`
+  * `config.log` from the build directory. When using `pyenv install` with `-k` as per above, the build directory will be under `$PYENV_ROOT/sources`.

+Make sure you have checked all steps below.
+
+### Prerequisite
+* [ ] Please consider implementing the feature as a hook script or plugin as a first step.
+  * pyenv has some powerful support for plugins and hook scripts. Please refer to [Authoring plugins](https://github.com/pyenv/pyenv/wiki/Authoring-plugins) for details and try to implement it as a plugin if possible.
+* [ ] Please consider contributing the patch upstream to [rbenv](https://github.com/rbenv/rbenv), since we have borrowed most of the code from that project.
+  * We occasionally import the changes from rbenv. In general, you can expect changes made in rbenv will be imported to pyenv too, eventually.
+  * Generally speaking, we prefer not to make changes in the core in order to keep compatibility with rbenv.
+* [ ] My PR addresses the following pyenv issue (if any)
+  - Closes https://github.com/pyenv/pyenv/issues/XXXX

+Like `git`, the `pyenv` command delegates to subcommands based on its
+first argument.
+
+The most common subcommands are:
+
+* [`pyenv help`](#pyenv-help)
+* [`pyenv commands`](#pyenv-commands)
+* [`pyenv local`](#pyenv-local)
+* [`pyenv global`](#pyenv-global)

+
+## `pyenv help`
+
+List all available pyenv commands along with a brief description of what they do. Run `pyenv help <command>` for information on a specific command. For full documentation, see: https://github.com/pyenv/pyenv#readme
+
+
+## `pyenv commands`
+
+Lists all available pyenv commands.
+
+
+## `pyenv local`
+
+Sets a local application-specific Python version by writing the version
+name to a `.python-version` file in the current directory. This version
+overrides the global version, and can be overridden itself by setting
+the `PYENV_VERSION` environment variable or with the `pyenv shell`
+command.
+
+    $ pyenv local 2.7.6
+
+When run without a version number, `pyenv local` reports the currently
+configured local version. You can also unset the local version:
+
+    $ pyenv local --unset
+
+Previous versions of pyenv stored local version specifications in a
+file named `.pyenv-version`. For backwards compatibility, pyenv will
+read a local version specified in an `.pyenv-version` file, but a
+`.python-version` file in the same directory will take precedence.
+
+
+### `pyenv local` (advanced)
+

+
+
+## `pyenv global`
+
+Sets the global version of Python to be used in all shells by writing
+the version name to the `~/.pyenv/version` file. This version can be
+overridden by an application-specific `.python-version` file, or by
+setting the `PYENV_VERSION` environment variable.
+
+    $ pyenv global 2.7.6
+
+The special version name `system` tells pyenv to use the system Python
+(detected by searching your `$PATH`).
+
+When run without a version number, `pyenv global` reports the
+currently configured global version.
+
+
+### `pyenv global` (advanced)
+
+You can specify multiple versions as global Python at once.
+
+Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
+
+    $ pyenv global 2.7.6 3.3.3
+    $ pyenv versions
+      system
+    * 2.7.6 (set by /Users/yyuu/.pyenv/version)
+    * 3.3.3 (set by /Users/yyuu/.pyenv/version)
+    $ python --version
+    Python 2.7.6
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+or, if you prefer 3.3.3 over 2.7.6,
+
+    $ pyenv global 3.3.3 2.7.6
+    $ pyenv versions
+      system
+    * 2.7.6 (set by /Users/yyuu/.pyenv/version)
+    * 3.3.3 (set by /Users/yyuu/.pyenv/version)
+      venv27
+    $ python --version
+    Python 3.3.3
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+
+## `pyenv shell`
+
+Sets a shell-specific Python version by setting the `PYENV_VERSION`
+environment variable in your shell. This version overrides
+application-specific versions and the global version.
+
+    $ pyenv shell pypy-2.2.1
+
+When run without a version number, `pyenv shell` reports the current
+value of `PYENV_VERSION`. You can also unset the shell version:
+
+    $ pyenv shell --unset
+
+Note that you'll need pyenv's shell integration enabled (step 3 of
+the installation instructions) in order to use this command. If you
+prefer not to use shell integration, you may simply set the
+`PYENV_VERSION` variable yourself:
+
+    $ export PYENV_VERSION=pypy-2.2.1
+
+
+### `pyenv shell` (advanced)
+
+You can specify multiple versions via `PYENV_VERSION` at once.
+
+Let's say if you have two versions of 2.7.6 and 3.3.3. If you prefer 2.7.6 over 3.3.3,
+
+    $ pyenv shell 2.7.6 3.3.3
+    $ pyenv versions
+      system
+    * 2.7.6 (set by PYENV_VERSION environment variable)
+    * 3.3.3 (set by PYENV_VERSION environment variable)
+    $ python --version
+    Python 2.7.6
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+or, if you prefer 3.3.3 over 2.7.6,
+
+    $ pyenv shell 3.3.3 2.7.6
+    $ pyenv versions
+      system
+    * 2.7.6 (set by PYENV_VERSION environment variable)
+    * 3.3.3 (set by PYENV_VERSION environment variable)
+      venv27
+    $ python --version
+    Python 3.3.3
+    $ python2.7 --version
+    Python 2.7.6
+    $ python3.3 --version
+    Python 3.3.3
+
+
+## `pyenv install`
+
+Install a Python version (using [`python-build`](https://github.com/pyenv/pyenv/tree/master/plugins/python-build)).
+
+    Usage: pyenv install [-f] [-kvp] <version>
+           pyenv install [-f] [-kvp] <definition-file>
+           pyenv install -l|--list
+
+      -l/--list             List all available versions
+      -f/--force            Install even if the version appears to be installed already
+      -s/--skip-existing    Skip the installation if the version appears to be installed already
+
+      python-build options:
+
+      -k/--keep        Keep source tree in $PYENV_BUILD_ROOT after installation
+                       (defaults to $PYENV_ROOT/sources)
+      -v/--verbose     Verbose mode: print compilation status to stdout
+      -p/--patch       Apply a patch from stdin before building
+      -g/--debug       Build a debug version
+
+To list the all available versions of Python, including Anaconda, Jython, pypy, and stackless, use:
+
+    $ pyenv install --list
+
+Then install the desired versions:
+
+    $ pyenv install 2.7.6
+    $ pyenv install 2.6.8
+    $ pyenv versions
+      system
+      2.6.8
+    * 2.7.6 (set by /home/yyuu/.pyenv/version)
+
+You can also install the latest version of Python in a specific version line by supplying a prefix instead of a complete name:
+
+    $ pyenv install 3.10
+
+See the [`pyenv latest` documentation](#pyenv-latest) for details on prefix resolution.
+
+An older option is to use the `:latest` syntax. For example, to install the latest patch version for Python 3.8 you could do:
+
+    pyenv install 3.8:latest
+
+To install the latest major release for Python 3 try:
+
+    pyenv install 3:latest
+
+## `pyenv uninstall`
+
+Uninstall Python versions.
+
+    Usage: pyenv uninstall [-f|--force] <version> ...
+
+       -f  Attempt to remove the specified version without prompting
+           for confirmation. If the version does not exist, do not
+           display an error message.
+
+
+## `pyenv rehash`
+
+Installs shims for all Python binaries known to pyenv (i.e.,
+`~/.pyenv/versions/*/bin/*`). Run this command after you install a new
+version of Python, or install a package that provides binaries.
+
+    $ pyenv rehash
+
+
+## `pyenv version`
+
+Displays the currently active Python version, along with information on
+how it was set.
+
+    $ pyenv version
+    2.7.6 (set by /home/yyuu/.pyenv/version)
+
+
+## `pyenv versions`
+
+Lists all Python versions known to pyenv, and shows an asterisk next to
+the currently active version.
+
+    $ pyenv versions
+      2.5.6
+      2.6.8
+    * 2.7.6 (set by /home/yyuu/.pyenv/version)
+      3.3.3
+      jython-2.5.3
+      pypy-2.2.1
+
+
+## `pyenv which`
+
+Displays the full path to the executable that pyenv will invoke when
+you run the given command.
+
+    $ pyenv which python3.3
+    /home/yyuu/.pyenv/versions/3.3.3/bin/python3.3
+
+Use --nosystem argument in case when you don't need to search command in the 
+system environment.
+
+## `pyenv whence`
+
+Lists all Python versions with the given command installed.
+
+    $ pyenv whence 2to3
+    2.6.8
+    2.7.6
+    3.3.3
+
+## `pyenv exec`
+
+    Usage: pyenv exec <command> [arg1 arg2...]
+
+Runs an executable by first preparing PATH so that the selected Python
+version's `bin` directory is at the front.
+
+For example, if the currently selected Python version is 3.9.7:
+
+    pyenv exec pip install -r requirements.txt
+    
+is equivalent to:
+
+    PATH="$PYENV_ROOT/versions/3.9.7/bin:$PATH" pip install -r requirements.txt
+
+## `pyenv root`
+
+Displays the root directory where versions and shims are kept.
+
+    $ pyenv root
+    /home/user/.pyenv
+
+## `pyenv prefix`
+
+Displays the directories where the given Python versions are installed,
+separated by colons. If no version is given, `pyenv prefix` displays the
+locations of the currently selected versions.
+
+    $ pyenv prefix 3.9.7
+    /home/user/.pyenv/versions/3.9.7
+
+## `pyenv latest`
+
+Displays the latest installed or known version with the given prefix
+
+    Usage: pyenv latest [-k|--known] [-q|--quiet] <prefix>
+
+     -k/--known      Select from all known versions instead of installed
+     -q/--quiet      Do not print an error message on resolution failure
+
+Only full prefixes are searched: in the actual name, the given prefix must be followed by a dot or a dash.
+
+Prereleases and versions with specific suffixes (e.g. `-src`) are ignored.
+
+## `pyenv hooks`
+
+Lists installed hook scripts for a given pyenv command.
+
+    Usage: pyenv hooks <command>
+
+## `pyenv shims`
+
+List existing pyenv shims.
+
+    Usage: pyenv shims [--short]
+
+    $ pyenv shims
+    /home/user/.pyenv/shims/2to3
+    /home/user/.pyenv/shims/2to3-3.9
+    /home/user/.pyenv/shims/idle
+    /home/user/.pyenv/shims/idle3

+    /home/user/.pyenv/shims/python3-config
+    /home/user/.pyenv/shims/python-config
+
+## `pyenv init`
+
+Configure the shell environment for pyenv
+
+    Usage: eval "$(pyenv init [-|--path] [--no-push-path] [--no-rehash] [<shell>])"
+
+      -                    Initialize shims directory, print PYENV_SHELL variable, completions path
+                           and shell function
+      --path               Print shims path
+      --no-push-path       Do not push shim to the start of PATH if they're already there
+      --no-rehash          Add no rehash command to output     
+
+## `pyenv completions`
+
+Lists available completions for a given pyenv command.
+
+    Usage: pyenv completions <command> [arg1 arg2...]

+General guidance
+================
+
+* The usual principles of respecting existing conventions and making sure that your changes
+  are in line with the overall product design apply when contributing code to Pyenv.
+
+* We are limited to Bash 3.2 features
+
+  That's because that's the version shipped with MacOS.
+  (They didn't upgrade past it and switched to Zsh because later versions
+  are covered by GPLv3 which has additional restrictions unacceptable for Apple.)
+
+  You can still add performance optimizations etc that take advantage of newer Bash features
+  as long as there is a fallback execution route for Bash 3.
+
+* Be extra careful when submitting logic specific for the Apple Silicon platform
+
+  As of this writing, Github Actions do not support it and only one team member has the necessary hardware.
+  So we may be unable to test your changes and may have to take your word for it.
+
+
+Formatting PRs
+==============
+
+We strive to keep commit history one-concern-per-commit to keep it meaningful and easy to follow.
+If a pull request (PR) addresses a single concern (the typical case), we usually squash commits
+from it together when merging so its commit history doesn't matter.
+If however a PR addresses multiple separate concerns, each of them should be presented as a separate commit.
+Adding multiple new Python releases of the same flavor is okay with either a single or multiple commits.
+
+
+Authoring installation scripts
+==============================
+
+Adding new Python release support
+---------------------------------
+
+The easiest way to add support for a new Python release is to copy the script from the previous one
+and adjust it as necessary. In many cases, just changing version numbers, URLs and hashes is enough.
+Do pay attention to other "magic numbers" that may be present in a script --
+e.g. the set of architectures and OS versions supported by a release -- since those change from time to time, too.
+
+Make sure to also copy any patches for the previous release that still apply to the new one.
+Typically, a patch no longer applies if it addresses a problem that's already fixed in the new release.
+
+For prereleases, we only create an entry for the latest prerelease in a specific version line.
+When submitting a newer prerelease, replace the older one.
+
+
+Adding version-specific fixes/patches
+-------------------------------------
+
+We accept fixes to issues in specific Python releases that prevent users from using them with Pyenv.
+
+In the default configuration for a Python release, we strive to provide as close to vanilla experience as practical,
+to maintain [the principle of the least surprise](https://en.wikipedia.org/wiki/Principle_of_least_astonishment).
+As such, any such fixes:
+
+* Must not break or degrade (e.g. disable features) the build in any of the environments that the release officially supports
+* Must not introduce incompatibilities with the vanilla release (including binary incompatibilities)
+* Should not patch things unnecessarily, to minimize the risk of the aforementioned undesirable side effects.
+  * E.g. if the fix is for a specific environment, its logic ought to only fire in this specific environment and not touch execution paths for other environments.
+  * As such, it's advisable to briefly explain in the PR what each added patch does and why it is necessary to fix the declared problem
+
+Generally, version-specific fixes belong in the scripts for the affected releases and/or patches for them -- this guarantees that their effect is limited to only those releases.
+
+<h3>Backporting upstream patches</h3>
+
+Usually, this is the easiest way to backport a fix for a problem that is fixed in a newer release.
+
+* Clone Python, check out the tag for the appropriate release and create a branch
+* Apply existing patches if there are any (with either `patch` or `git am`) and commit
+* Cherry-pick the upstream commit that fixes the problem in a newer release
+* Commit and `git format-patch`
+* Commit the generated patch file into Pyenv, test your changes and submit a PR
+
+
+Deprecation policy
+------------------
+
+We do not provide official support for EOL releases and environments or otherwise provide any kind of extended support for old Python releases.
+
+We do however accept fixes from interested parties that would allow running older, including EOL, releases in environments that they do not officially support.
+In addition to the above requirements for release-specific fixes,
+
+* Such a fix must not add maintenance burden (e.g. add new logic to `python-build` that has to be kept there indefinitely)
+  * Unless the added logic is useful for both EOL and non-EOL releases. In this case, it will be considered as being primarily an improvement for non-EOL releases.
+* Support is provided on a "best effort" basis: we do not actively maintain these fixes but won't actively break them, either, and will accept any corrections.
+  Since old releases never change, it's pretty safe to assume that the fixes will continue to work until a later version
+  of an environment introduces further incompatible changes.
+
+
+Advanced changes / adding new Python flavor support
+---------------------------------------------------
+
+An installation script is sourced from `python-build`. All installation scripts are based on the same logic:
+
+1. Select the source to download and other variable parameters as needed.
+
+   This includes showing an error if the user's environment (OS, architecture) is not supported by the release.
+   Binary releases that only officially support specific distro(s) typically show a warning in other distros instead.
+
+2. Run one of the `install_*` shell functions
+
+`install_*` shell functions defined in `python-build` install Python from different kinds of sources -- compressed package (binary or source), upstream installation script, VCS checkout. Pick one that's the most appropriate for your packaging.
+
+Each of them accepts a couple of function-specific arguments which are followed by arguments that constitute the build sequence. Each `<argument>` in the build sequence corresponds to the `install_*_<argument>` function in `python-build`. Check what's available and add any functions with logic specific to your flavor if needed.
+
+We strive to keep out of `python-build` parts of build logic that are release-specific and/or tend to change abruptly between releases -- e.g. sets of supported architectures and other software's versions. This results in logic duplication between installation scripts -- but since old releases never change once released, this doesn't really add to the maintenance burden. As a rule of thumb, `python-build` can host parts of logic that are expected to stay the same for an indefinite amount of time -- for an entire Python flavor or release line.

+Creating a release
+==================
+
+The release of the new version of Pyenv is done via GitHub Releases.
+
+Release checklist:
+* Start [drafting a new release on GitHub](https://github.com/pyenv/pyenv/releases) to generate a summary of changes. Save the summary locally.
+  * The summary may need editing. E.g. rephrase entries, delete/merge entries that are too minor or irrelevant to the users (e.g. typo fixes, CI)
+* Push the version number in `libexec/pyenv---version`
+  * Minor version is pushed if there are significant functional changes (not e.g. bugfixes/formula adaptations/supporting niche use cases).
+  * Major version is pushed if there are breaking changes
+* Update `CHANGELOG.md` with the new version number and the edited summary (only the changes section), reformatting it like the rest of the changelog sections
+* Commit the changes locally into `master`
+* Create a new tag with the new version number and push the changes including the tag
+* Create a new release on GitHub based on the tag, using the saved summary

-# Simple Ruby Version Management: rbenv
-
-rbenv lets you easily switch between multiple versions of Ruby. It's
-simple, unobtrusive, and follows the UNIX tradition of single-purpose
-tools that do one thing well.
-
-<img src="http://i.sstephenson.us/rbenv2.png" width="894" height="464">
-
-### rbenv _does…_
-
-* Let you **change the global Ruby version** on a per-user basis.
-* Provide support for **per-project Ruby versions**.
-* Allow you to **override the Ruby version** with an environment
-  variable.
-
-### In contrast with rvm, rbenv _does not…_
-
-* **Need to be loaded into your shell.** Instead, rbenv's shim
-    approach works by adding a directory to your `$PATH`.
-* **Override shell commands like `cd`.** That's dangerous and
-    error-prone.
-* **Have a configuration file.** There's nothing to configure except
-    which version of Ruby you want to use.
-* **Install Ruby.** You can build and install Ruby yourself, or use
-    [ruby-build](https://github.com/sstephenson/ruby-build) to
-    automate the process.
-* **Manage gemsets.** [Bundler](http://gembundler.com/) is a better
-    way to manage application dependencies. If you have projects that
-    are not yet using Bundler you can install the
-    [rbenv-gemset](https://github.com/jamis/rbenv-gemset) plugin.
-* **Require changes to Ruby libraries for compatibility.** The
-    simplicity of rbenv means as long as it's in your `$PATH`,
-    [nothing](https://rvm.beginrescueend.com/integration/bundler/)
-    [else](https://rvm.beginrescueend.com/integration/capistrano/)
-    needs to know about it.
-* **Prompt you with warnings when you switch to a project.** Instead
-    of executing arbitrary code, rbenv reads just the version name
-    from each project. There's nothing to "trust."
-
-## Table of Contents
-
-## How It Works ##
-
-rbenv operates on the per-user directory `~/.rbenv`. Version names in
-rbenv correspond to subdirectories of `~/.rbenv/versions`. For
-example, you might have `~/.rbenv/versions/1.8.7-p354` and
-`~/.rbenv/versions/1.9.3-rc1`.
-
-Each version is a working tree with its own binaries, like
-`~/.rbenv/versions/1.8.7-p354/bin/ruby` and
-`~/.rbenv/versions/1.9.3-rc1/bin/irb`. rbenv makes _shim binaries_
-for every such binary across all installed versions of Ruby.
-
-These shims are simple wrapper scripts that live in `~/.rbenv/shims`
-and detect which Ruby version you want to use. They insert the
-directory for the selected version at the beginning of your `$PATH`
-and then execute the corresponding binary.
-
-Because of the simplicity of the shim approach, all you need to use
-rbenv is `~/.rbenv/shims` in your `$PATH`.
-
-## Installation ##
-
-**Compatibility note**: rbenv is _incompatible_ with rvm. Things will
-  appear to work until you try to install a gem. The problem is that
-  rvm actually overrides the `gem` command with a shell function!
-  Please remove any references to rvm before using rbenv.
-
-### Basic GitHub Checkout ###
-
-This will get you going with the latest version of rbenv and make it
-easy to fork and contribute any changes back upstream.
-
-1. Check out rbenv into `~/.rbenv`.
-
-        $ cd
-        $ git clone git://github.com/sstephenson/rbenv.git .rbenv
-
-2. Add `~/.rbenv/bin` to your `$PATH` for access to the `rbenv`
-   command-line utility.
-
-        $ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
-
-    **Zsh note**: Modifiy your `~/.zshenv` file instead of `~/.bash_profile`.
-
-3. Add rbenv init to your shell to enable shims and autocompletion.
-
-        $ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
-
-    **Zsh note**: Modifiy your `~/.zshenv` file instead of `~/.bash_profile`.
-
-4. Restart your shell so the path changes take effect. You can now
-   begin using rbenv.
-
-        $ exec $SHELL
-
-5. Install Ruby versions into `~/.rbenv/versions`. For example, to
-   install Ruby 1.9.2-p290, download and unpack the source, then run:
-
-        $ ./configure --prefix=$HOME/.rbenv/versions/1.9.2-p290
-        $ make
-        $ make install
-
-    The [ruby-build](https://github.com/sstephenson/ruby-build) project
-    provides an `rbenv install` command that simplifies the process of
-    installing new Ruby versions to:
-
-        $ rbenv install 1.9.2-p290
-
-6. Rebuild the shim binaries. You should do this any time you install
-   a new Ruby binary (for example, when installing a new Ruby version,
-   or when installing a gem that provides a binary).
-
-        $ rbenv rehash
-
-#### Upgrading ####
-
-If you've installed rbenv using the instructions above, you can
-upgrade your installation at any time using git.
-
-To upgrade to the latest development version of rbenv, use `git pull`:
-
-    $ cd ~/.rbenv
-    $ git pull
-
-To upgrade to a specific release of rbenv, check out the corresponding
-tag:
-
-    $ cd ~/.rbenv
-    $ git fetch
-    $ git tag
-    v0.1.0
-    v0.1.1
-    v0.1.2
-    v0.2.0
-    $ git checkout v0.2.0
-
-### Homebrew on Mac OS X ###
-
-You can also install rbenv using the
-[Homebrew](http://mxcl.github.com/homebrew/) package manager on Mac OS
-X.
-
-    $ brew update
-    $ brew install rbenv
-    $ brew install ruby-build
-
-The same commands can be used for upgrading.
-
-Afterwards you'll still need to add `eval "$(rbenv init -)"` to your
-profile as stated in the caveats. You'll only ever have to do this
-once.
-
-### Neckbeard Configuration ###
-
-Skip this section unless you must know what every line in your shell
-profile is doing.
-
-`rbenv init` is the only command that crosses the line of loading
-extra commands into your shell. Coming from rvm, some of you might be
-opposed to this idea. Here's what `rbenv init` actually does:
-
-1. Sets up your shims path. This is the only requirement for rbenv to
-   function properly. You can do this by hand by prepending
-   `~/.rbenv/shims` to your `$PATH`.
-
-2. Installs autocompletion. This is entirely optional but pretty
-   useful. Sourcing `~/.rbenv/completions/rbenv.bash` will set that
-   up. There is also a `~/.rbenv/completions/rbenv.zsh` for Zsh
-   users.
-
-3. Rehashes shims. From time to time you'll need to rebuild your
-   shim files. Doing this on init makes sure everything is up to
-   date. You can always run `rbenv rehash` manually.
-
-4. Installs the sh dispatcher. This bit is also optional, but allows
-   rbenv and plugins to change variables in your current shell, making
-   commands like `rbenv shell` possible. The sh dispatcher doesn't do
-   anything crazy like override `cd` or hack your shell prompt, but if
-   for some reason you need `rbenv` to be a real script rather than a
-   shell function, you can safely skip it.
-
-Run `rbenv init -` for yourself to see exactly what happens under the
-hood.
-
-## Usage ##
-
-Like `git`, the `rbenv` command delegates to subcommands based on its
-first argument. The most common subcommands are:
-
-### rbenv global ###
-
-Sets the global version of Ruby to be used in all shells by writing
-the version name to the `~/.rbenv/version` file. This version can be
-overridden by a per-project `.rbenv-version` file, or by setting the
-`RBENV_VERSION` environment variable.
-
-    $ rbenv global 1.9.2-p290
-
-The special version name `system` tells rbenv to use the system Ruby
-(detected by searching your `$PATH`).
-
-When run without a version number, `rbenv global` reports the
-currently configured global version.
-
-### rbenv local ###
-
-Sets a local per-project Ruby version by writing the version name to
-an `.rbenv-version` file in the current directory. This version
-overrides the global, and can be overridden itself by setting the
-`RBENV_VERSION` environment variable or with the `rbenv shell`
-command.
-
-    $ rbenv local rbx-1.2.4
-
-When run without a version number, `rbenv local` reports the currently
-configured local version. You can also unset the local version:
-
-    $ rbenv local --unset
-
-### rbenv shell ###
-
-Sets a shell-specific Ruby version by setting the `RBENV_VERSION`
-environment variable in your shell. This version overrides both
-project-specific versions and the global version.
-
-    $ rbenv shell jruby-1.6.4
-
-When run without a version number, `rbenv shell` reports the current
-value of `RBENV_VERSION`. You can also unset the shell version:
-
-    $ rbenv shell --unset
-
-Note that you'll need rbenv's shell integration enabled (step 3 of
-the installation instructions) in order to use this command. If you
-prefer not to use shell integration, you may simply set the
-`RBENV_VERSION` variable yourself:
-
-    $ export RBENV_VERSION=jruby-1.6.4
-
-### rbenv versions ###
-
-Lists all Ruby versions known to rbenv, and shows an asterisk next to
-the currently active version.
-
-    $ rbenv versions
-      1.8.7-p352
-      1.9.2-p290
-    * 1.9.3-rc1 (set by /Users/sam/.rbenv/global)
-      jruby-1.6.4
-      rbx-1.2.4
-      ree-1.8.7-2011.03
-
-### rbenv version ###
-
-Displays the currently active Ruby version, along with information on
-how it was set.
-
-    $ rbenv version
-    1.8.7-p352 (set by /Volumes/37signals/basecamp/.rbenv-version)
-
-### rbenv rehash ###
-
-Installs shims for all Ruby binaries known to rbenv (i.e.,
-`~/.rbenv/versions/*/bin/*`). Run this command after you install a new
-version of Ruby, or install a gem that provides binaries.
-
-    $ rbenv rehash
-
-### rbenv which ###
-
-Displays the full path to the binary that rbenv will execute when you
-run the given command.
-
-    $ rbenv which irb
-    /Users/sam/.rbenv/versions/1.9.2-p290/bin/irb
-
-### rbenv whence ###
-
-Lists all Ruby versions with the given command installed.
-
-    $ rbenv whence rackup
-    1.9.3-rc1
-    jruby-1.6.4
-    ree-1.8.7-2011.03
-
-## Development ##
-
-The rbenv source code is [hosted on
-GitHub](https://github.com/sstephenson/rbenv). It's clean, modular,
-and easy to understand, even if you're not a shell hacker.
-
-Please feel free to submit pull requests and file bugs on the [issue
-tracker](https://github.com/sstephenson/rbenv/issues).
-
-### Version History ###
-
-**0.3.0** (December 25, 2011)
-
-* Added an `rbenv root` command which prints the value of
-  `$RBENV_ROOT`, or the default root directory if it's unset.
-* Clarified Zsh installation instructions in the readme.
-* Removed some redundant code in `rbenv rehash`.
-* Fixed an issue with calling `readlink` for paths with spaces.
-* Changed Zsh initialization code to install completion hooks only for
-  interactive shells.
-* Added preliminary support for ksh.
-* `rbenv rehash` creates or removes shims only when necessary instead
-  of removing and re-creating all shims on each invocation.
-* Fixed that `RBENV_DIR`, when specified, would be incorrectly
-  expanded to its parent directory.
-* Removed the deprecated `set-default` and `set-local` commands.
-* Added a `--no-rehash` option to `rbenv init` for skipping the
-  automatic rehash when opening a new shell.
-
-**0.2.1** (October 1, 2011)
-
-* Changed the `rbenv` command to ensure that `RBENV_DIR` is always an
-  absolute path. This fixes an issue where Ruby scripts using the
-  `ruby-local-exec` wrapper would go into an infinite loop when
-  invoked with a relative path from the command line.
-
-**0.2.0** (September 28, 2011)
-
-* Renamed `rbenv set-default` to `rbenv global` and `rbenv set-local`
-  to `rbenv local`. The `set-` commands are deprecated and will be
-  removed in the next major release.
-* rbenv now uses `greadlink` on Solaris.
-* Added a `ruby-local-exec` command which can be used in shebangs in
-  place of `#!/usr/bin/env ruby` to properly set the project-specific
-  Ruby version regardless of current working directory.
-* Fixed an issue with `rbenv rehash` when no binaries are present.
-* Added support for `rbenv-sh-*` commands, which run inside the
-  current shell instead of in a child process.
-* Added an `rbenv shell` command for conveniently setting the
-  `$RBENV_VERSION` environment variable.
-* Added support for storing rbenv versions and shims in directories
-  other than `~/.rbenv` with the `$RBENV_ROOT` environment variable.
-* Added support for debugging rbenv via `set -x` when the
-  `$RBENV_DEBUG` environment variable is set.
-* Refactored the autocompletion system so that completions are now
-  built-in to each command and shared between bash and Zsh.
-* Added support for plugin bundles in `~/.rbenv/plugins` as documented
-  in [issue #102](https://github.com/sstephenson/rbenv/pull/102).
-* Added `/usr/local/etc/rbenv.d` to the list of directories searched
-  for rbenv hooks.
-* Added support for an `$RBENV_DIR` environment variable which
-  defaults to the current working directory for specifying where rbenv
-  searches for local version files.
-
-**0.1.2** (August 16, 2011)
-
-* Fixed rbenv to be more resilient against nonexistent entries in
-  `$PATH`.
-* Made the `rbenv rehash` command operate atomically.
-* Modified the `rbenv init` script to automatically run `rbenv
-  rehash` so that shims are recreated whenever a new shell is opened.
-* Added initial support for Zsh autocompletion.
-* Removed the dependency on egrep for reading version files.
-
-**0.1.1** (August 14, 2011)
-
-* Fixed a syntax error in the `rbenv help` command.
-* Removed `-e` from the shebang in favor of `set -e` at the top of
-  each file for compatibility with operating systems that do not
-  support more than one argument in the shebang.
-
-**0.1.0** (August 11, 2011)
-
-* Initial public release.

+pyenv \- Simple Python version management
+.SH SYNOPSIS
+.B pyenv
+\fI\,<command> \/\fR[\fI\,<args>\/\fR]
+.SH DESCRIPTION
+pyenv lets you easily switch between multiple versions of Python\. It's simple, unobtrusive, and follows the UNIX tradition of single\-purpose tools that do one thing well\.
+.P
+ To start using pyenv
+.IP "1." 3
+\fBAppend\fR the following to \fB$HOME/.bashrc\fR
+.P
+.RS 15
+.nf
+if command -v pyenv 1>/dev/null 2>&1; then\n
+   eval "$(pyenv init -)" \n
+fi
+.fi
+.RE
+.RS 3
+.P
+.nh
+Appending this line enables shims. Please make sure this line is placed toward the end of the shell configuration file since it manipulates \fBPATH\fR during the initialization\. 
+.hy
+.TP 13
+.B Debian note:
+Modify only your \fB~/\.bashrc\fR file instead of creating 
+.br
+\fB~/\.bash_profile\fR
+.P
+.RS 0
+\fBZsh note\fR: Modify your \fB~/\.zshrc\fR file instead of  \fB~/\.bashrc\fR
+.P
+\fBWarning\fR: If you configured your system so  that \fBBASH_ENV\fR variable  points to \fB\.bashrc\fR\. You should almost certainly put the above mentioned line  into \fB\.bash_profile\fR, and \fBnot\fR into \fB\.bashrc\fR. Otherwise you may observe strange behaviour, such as \fBpyenv\fR getting into an infinite loop. See #264 
+.UR https://github\.com/pyenv/pyenv/issues/264
+.UE
+for details.

+\fBInstall Python versions into \fB$(pyenv root)/versions\fR\.\fR For example, to download and install Python 3\.6\.12, run:
+.P
+.RS 15
+.B pyenv install 3.6.12\fR 
+.RE
+.P
+\fBNOTE:\fR If you need to pass configure option to build, please use \fBCONFIGURE_OPTS\fR environment variable. If you are having trouble installing a python version, please visit the wiki page about Common Build Problems
+.UR https://github\.com/pyenv/pyenv/wiki/Common\-build\-problems
+.UE
+.P
+\fBProxy note\fR: If you use a proxy, export \fBHTTP_PROXY\fR and \fBHTTPS_PROXY\fR environment variables.
+.P
+.SS "Stop using pyenv"
+The simplicity of pyenv makes it easy to temporarily disable it, or uninstall from the system\.
+To \fBdisable\fR pyenv managing your Python versions, simply remove the \fBpyenv init\fR line from your shell startup configuration\. This will remove pyenv shims directory from PATH, and future invocations like \fBpython\fR will execute the system Python version, as before pyenv\.
+.IP "" 0
+.P
+\fBpyenv\fR will still be accessible on the command line, but your Python apps won't be affected by version switching\.
+.IP "" 0
+.SH COMMAND LINE OPTIONS
+Like \fBgit\fR, the \fBpyenv\fR command delegates to subcommands based on its first argument\.
+.SS "Some useful pyenv commands are:"
+.TP 5
+.B commands
+List all available pyenv commands
+.TP
+.B exec
+Run an executable with the selected Python version
+.TP
+.B global
+Set or show the global Python version(s)

+Display help for a command
+.TP
+.B hooks
+List hook scripts for a given pyenv command
+.TP
+.B init
+Configure the shell environment for pyenv

+.B install
+Install a Python version using python\-build
+.TP

+.IP \(bu 4
+\fBDepend on Python itself\.\fR pyenv was made from pure shell scripts\. There is no bootstrap problem of Python\.
+.IP \(bu 4
+\fBNeed to be loaded into your shell\.\fR Instead, pyenv's shim approach works by adding a directory to your \fB$PATH\fR\.
+.IP \(bu 4
+\fBManage virtualenv\.\fR Of course, you can create virtualenv  yourself, or pyenv\-virtualenv  to automate the process\.
+.SH "How It Works"
+At a high level, pyenv intercepts Python commands using shim executables injected into your \fBPATH\fR, determines which Python version has been specified by your application, and passes your commands along to the correct Python installation\.
+.SS "Understanding PATH"
+When you run a command like \fBpython\fR or \fBpip\fR, your operating system searches through a list of directories to find an executable file with that name\. This list of directories lives in an environment variable called \fBPATH\fR, with each directory in the list separated by a colon:
+.IP "" 4
+.nf
+/usr/local/bin:/usr/bin:/bin
+.fi
+.IP "" 0
+.P
+Directories in \fBPATH\fR are searched from left to right, so a matching executable in a directory at the beginning of the list takes precedence over another one at the end\. In this example, the \fB/usr/local/bin\fR directory will be searched first, then \fB/usr/bin\fR, then \fB/bin\fR\.
+.SS "Understanding Shims"
+pyenv works by inserting a directory of \fIshims\fR at the front of your \fBPATH\fR:
+.IP "" 4
+.nf
+$(pyenv root)/shims:/usr/local/bin:/usr/bin:/bin
+.fi
+.IP "" 0
+.P
+Through a process called \fIrehashing\fR, pyenv maintains shims in that directory to match every Python command (\fBpython\fR,\fBpip\fR,etc...) across every installed version of Python 
+.P
+Shims are lightweight executables that simply pass your command along to pyenv\. So with pyenv installed, when you run, say, \fBpip\fR, your operating system will do the following:
+.IP \(bu 4
+Search your \fBPATH\fR for an executable file named \fBpip\fR
+.IP \(bu 4
+Find the pyenv shim named \fBpip\fR at the beginning of your \fBPATH\fR
+.IP \(bu 4
+Run the shim named \fBpip\fR, which in turn passes the command along to pyenv
+.IP "" 0
+.SS "Choosing the Python Version"
+When you execute a shim, pyenv determines which Python version to use by reading it from the following sources, in this order:
+.IP "1." 4
+The \fBPYENV_VERSION\fR environment variable (if specified)\. You can use the \fBpyenv shell\fR command to set this environment variable in your current shell session\.
+.IP "2." 4
+The application\-specific \fB\.python\-version\fR file in the current directory (if present)\. You can modify the current directory's \fB\.python\-version\fR file with the \fBpyenv local\fR command\.
+.IP "3." 4
+The first \fB\.python\-version\fR file found (if any) by searching each parent directory, until reaching the root of your filesystem\.
+.IP "4." 4
+The global \fB$(pyenv root)/version\fR file\. You can modify this file using the \fBpyenv global\fR  command\. If the global version file is not present, pyenv assumes you want to use the "system" Python\. (In other words, whatever version would run if pyenv weren't in your \fBPATH\fR\.)
+.IP "" 0
+.P
+.nh
+\fBNOTE:\fR You can activate multiple versions at the same time, including multiple versions of Python2 or Python3 simultaneously\. This allows for parallel usage of Python2 and Python3, and is required with tools like \fBtox\fR\. For example, to set your path to first use your \fBsystem\fR Python and Python3 (set to 2\.7\.9 and 3\.4\.2 in this example), but also have Python 3\.3\.6, 3\.2, and 2\.5 available on your \fBPATH\fR, one would first \fBpyenv install\fR the missing versions, then set \fBpyenv global system 3\.3\.6 3\.2 2\.5\fR\. At this point, one should be able to find the full executable path to each of these using \fBpyenv which\fR, e\.g\. \fBpyenv which python2\.5\fR (should display \fB$(pyenv root)/versions/2\.5/bin/python2\.5\fR), or \fBpyenv which python3\.4\fR (should display path to system Python3)\. You can also specify multiple versions in a \fB\.python\-version\fR file, separated by newlines or any whitespace\.
+hy
+.SS "Locating the Python Installation"
+Once pyenv has determined which version of Python your application has specified, it passes the command along to the corresponding Python installation\.
+.P
+Each Python version is installed into its own directory under 
+.nf
+\fB$(pyenv root)/versions\fR\.
+.fi
+.P
+For example, you might have these versions installed:
+.IP \(bu 4
+\fB$(pyenv root)/versions/2\.7\.8/\fR
+.IP \(bu 4
+\fB$(pyenv root)/versions/3\.4\.2/\fR
+.IP \(bu 4
+\fB$(pyenv root)/versions/pypy\-2\.4\.0/\fR
+.IP "" 0
+.P
+As far as pyenv is concerned, version names are simply the directories in \fB$(pyenv root)/versions\fR\.
+.SS "Managing Virtual Environments"
+There is a pyenv plugin named pyenv\-virtualenv which comes with various features to help pyenv users to manage virtual environments created by virtualenv or Anaconda\. Because the \fBactivate\fR script of those virtual environments are relying on mutating \fB$PATH\fR variable of user's interactive shell, it will intercept pyenv's shim style command execution hooks\. We'd recommend to install pyenv\-virtualenv as well if you have some plan to play with those virtual environments\.
+
+.SH "Advanced Configuration"
+Skip this section unless you must know what every line in your shell profile is doing\.
+.P
+\fBpyenv init\fR is the only command that crosses the line of loading extra commands into your shell\. Coming from rvm, some of you might be opposed to this idea\. Here's what \fBpyenv init\fR actually does:
+.IP "1." 4
+\fBSets up your shims path\.\fR This is the only requirement for pyenv to function properly\. You can do this by hand by prepending \fB$(pyenv root)/shims\fR to your \fB$PATH\fR\.
+.IP "2." 4
+\fBRehashes shims\.\fR From time to time you'll need to rebuild your shim files\. Doing this on init makes sure everything is up to date\. You can always run \fBpyenv rehash\fR manually\.
+You can disable this functionality by adding \fB--no-rehash\fR to the end of your \fBpyenv init\fR command line.
+.IP "3." 4
+\fBInstalls the sh dispatcher\.\fR This bit is also optional, but allows pyenv and plugins to change variables in your current shell, making commands like \fBpyenv shell\fR possible\. The sh dispatcher doesn't do anything crazy like override \fBcd\fR or hack your shell prompt, but if for some reason you need \fBpyenv\fR to be a real script rather than a shell function, you can safely skip it\.
+.IP "" 0
+.P
+To see exactly what happens under the hood for yourself, run \fB"pyenv init \-"\fR\.
+.SH "Uninstalling Python Versions"
+As time goes on, you will accumulate Python versions in your \fB$(pyenv root)/versions\fR directory\.
+.P
+To remove old Python versions, \fBpyenv uninstall\fR command to automate the removal process\.
+.P
+Alternatively, simply \fBrm \-rf\fR the directory of the version you want to remove\. You can find the directory of a particular Python version with the \fBpyenv prefix\fR command, 
+.P
+e\.g\. \fBpyenv prefix 2\.6\.8\fR\.
+.SH "Command Reference"
+.P
+The most common subcommands are:
+.SS "pyenv commands"
+Lists all available pyenv commands\.
+.SS "pyenv local"
+Sets a local application\-specific Python version by writing the version name to a \fB\.python\-version\fR file in the current directory\. This version overrides the global version, and can be overridden itself by setting the \fBPYENV_VERSION\fR environment variable or with the \fBpyenv shell\fR command\.
+.IP "" 4
+.nf
+$ pyenv local 2\.7\.6
+.fi
+.IP "" 0
+.P
+When run without a version number, \fBpyenv local\fR reports the currently configured local version\. You can also unset the local version:
+.IP "" 4
+.nf
+$ pyenv local \-\-unset
+.fi
+.IP "" 0
+.P
+Previous versions of pyenv stored local version specifications in a file named \fB\.pyenv\-version\fR\. For backwards compatibility, pyenv will read a local version specified in an \fB\.pyenv\-version\fR file, but a \fB\.python\-version\fR file in the same directory will take precedence\.
+.P
+You can specify multiple versions as local Python at once\.

+# python-build
+
+python-build is a [pyenv](https://github.com/pyenv/pyenv) plugin that
+provides a `pyenv install` command to compile and install different versions
+of Python on UNIX-like systems.
+
+You can also use python-build without pyenv in environments where you need
+precise control over Python version installation.
+
+See the [list of releases](https://github.com/pyenv/pyenv/releases)
+for changes in each version.
+
+
+## Installation
+
+### Installing as a pyenv plugin (recommended)
+
+Since python-build is bundled with pyenv by
+default, you do not need to do anything.
+
+### Installing as a standalone program (advanced)
+
+Installing python-build as a standalone program will give you access to the
+`python-build` command for precise control over Python version installation. If you
+have pyenv installed, you will also be able to use the `pyenv install` command.
+
+    git clone https://github.com/pyenv/pyenv.git
+    cd pyenv/plugins/python-build
+    ./install.sh
+
+This will install python-build into `/usr/local`. If you do not have write
+permission to `/usr/local`, you will need to run `sudo ./install.sh` instead.
+You can install to a different prefix by setting the `PREFIX` environment
+variable.
+
+To update python-build after it has been installed, run `git pull` in your cloned
+copy of the repository, then re-run the install script.
+
+### Installing with Homebrew (for OS X users)
+
+Mac OS X users can install python-build with the [Homebrew](http://brew.sh)
+package manager. This will give you access to the `python-build` command. If you
+have pyenv installed, you will also be able to use the `pyenv install` command.
+
+*This is the recommended method of installation if you installed pyenv with
+Homebrew.*
+
+    brew install pyenv
+
+Or, if you would like to install the latest development release:
+
+    brew install --HEAD pyenv
+
+
+## Usage
+
+Before you begin, you should ensure that your build environment has the proper
+system dependencies for compiling the wanted Python Version (see our [recommendations](https://github.com/pyenv/pyenv/wiki#suggested-build-environment)).
+
+### Using `pyenv install` with pyenv
+
+To install a Python version for use with pyenv, run `pyenv install` with
+exact name of the version you want to install. For example,
+
+    pyenv install 2.7.4
+
+Python versions will be installed into a directory of the same name under
+`~/.pyenv/versions`.
+
+To see a list of all available Python versions, run `pyenv install --list`. You
+may also tab-complete available Python versions if your pyenv installation is
+properly configured.
+
+### Using `python-build` standalone
+
+If you have installed python-build as a standalone program, you can use the
+`python-build` command to compile and install Python versions into specific
+locations.
+
+Run the `python-build` command with the exact name of the version you want to
+install and the full path where you want to install it. For example,
+
+    python-build 2.7.4 ~/local/python-2.7.4
+
+To see a list of all available Python versions, run `python-build --definitions`.
+
+Pass the `-v` or `--verbose` flag to `python-build` as the first argument to see
+what's happening under the hood.
+
+### Custom definitions
+
+Both `pyenv install` and `python-build` accept a path to a custom definition file
+in place of a version name. Custom definitions let you develop and install
+versions of Python that are not yet supported by python-build.
+
+See the [python-build built-in definitions](https://github.com/pyenv/pyenv/tree/master/plugins/python-build/share/python-build) as a starting point for
+custom definition files.
+
+[definitions]: https://github.com/pyenv/pyenv/tree/master/plugins/python-build/share/python-build
+
+### Special environment variables
+
+You can set certain environment variables to control the build process.
+
+* `TMPDIR` sets the location where python-build stores temporary files.
+* `PYTHON_BUILD_BUILD_PATH` sets the location in which sources are downloaded and
+  built. By default, this is a subdirectory of `TMPDIR`.
+* `PYTHON_BUILD_CACHE_PATH`, if set, specifies a directory to use for caching
+  downloaded package files.
+* `PYTHON_BUILD_MIRROR_URL` overrides the default mirror URL root to one of your
+  choosing.
+* `PYTHON_BUILD_MIRROR_URL_SKIP_CHECKSUM`, if set, does not append the SHA2
+  checksum of the file to the mirror URL.
+* `PYTHON_BUILD_SKIP_MIRROR`, if set, forces python-build to download packages from
+  their original source URLs instead of using a mirror.
+* `PYTHON_BUILD_HTTP_CLIENT`, explicitly specify the HTTP client type to use. `aria2`, `curl` and `wget` are the supported values and by default, are searched in that order.
+* `PYTHON_BUILD_SKIP_HOMEBREW`, if set, will not search for libraries installed by Homebrew in macOS.
+* `PYTHON_BUILD_HOMEBREW_OPENSSL_FORMULA`, override the Homebrew OpenSSL formula to use.
+* `PYTHON_BUILD_ROOT` overrides the default location from where build definitions
+  in `share/python-build/` are looked up.
+* `PYTHON_BUILD_DEFINITIONS` can be a list of colon-separated paths that get
+  additionally searched when looking up build definitions.
+* `CC` sets the path to the C compiler.
+* `PYTHON_CFLAGS` lets you pass additional options to the default `CFLAGS`. Use
+  this to override, for instance, the `-O3` option.
+* `CONFIGURE_OPTS` lets you pass additional options to `./configure`.
+* `MAKE` lets you override the command to use for `make`. Useful for specifying
+  GNU make (`gmake`) on some systems.
+* `MAKE_OPTS` (or `MAKEOPTS`) lets you pass additional options to `make`.
+* `MAKE_INSTALL_OPTS` lets you pass additional options to `make install`.
+* `PYTHON_CONFIGURE_OPTS` and `PYTHON_MAKE_OPTS` and `PYTHON_MAKE_INSTALL_OPTS` allow
+  you to specify configure and make options for building CPython. These variables
+  will be passed to Python only, not any dependent packages (e.g. libyaml).
+
+### Applying patches to Python before compiling
+
+Both `pyenv install` and `python-build` support the `--patch` (`-p`) flag that
+signals that a patch from stdin should be applied to Python, Jython or PyPy
+source code before the `./configure` and compilation steps.
+
+Example usage:
+
+```sh
+# applying a single patch
+$ pyenv install --patch 2.7.10 < /path/to/python.patch
+
+# applying a patch from HTTP
+$ pyenv install --patch 2.7.10 < <(curl -sSL http://git.io/python.patch)
+
+# applying multiple patches
+$ cat fix1.patch fix2.patch | pyenv install --patch 2.7.10
+```
+
+
+### Building with `--enable-shared`
+
+You can build CPython with `--enable-shared` to install a version with
+shared object.
+
+If `--enable-shared` was found in `PYTHON_CONFIGURE_OPTS` or `CONFIGURE_OPTS`,
+`python-build` will automatically set `RPATH` to the pyenv's prefix directory.
+This means you don't have to set `LD_LIBRARY_PATH` or `DYLD_LIBRARY_PATH` for
+the version(s) installed with `--enable-shared`.
+
+```sh
+$ env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 2.7.9
+```
+
+### Building for maximum performance
+
+Building CPython with `--enable-optimizations` will result in a faster
+interpreter at the cost of significantly longer build times. Most notably, this
+enables PGO (profile guided optimization). While your mileage may vary, it is
+common for performance improvement from this to be in the ballpark of 30%.
+
+```sh
+env PYTHON_CONFIGURE_OPTS='--enable-optimizations --with-lto' PYTHON_CFLAGS='-march=native -mtune=native' pyenv install 3.6.0
+```
+
+You can also customize the task used for profile guided optimization by setting
+the `PROFILE_TASK` environment variable, for instance, `PROFILE_TASK='-m
+test.regrtest --pgo -j0'` will run much faster than the default task.
+
+### Checksum verification
+
+If you have the `shasum`, `openssl`, or `sha256sum` tool installed, python-build will
+automatically verify the SHA2 checksum of each downloaded package before
+installing it.
+
+Checksums are optional and specified as anchors on the package URL in each
+definition. (All bundled definitions include checksums.)
+
+### Package download mirrors
+
+python-build will first attempt to download package files from a mirror hosted on
+GitHub Pages. If a package is not available on the mirror, if the mirror
+is down, or if the download is corrupt, python-build will fall back to the
+official URL specified in the definition file.
+
+You can point python-build to another mirror by specifying the
+`PYTHON_BUILD_MIRROR_URL` environment variable--useful if you'd like to run your
+own local mirror, for example. Package mirror URLs are constructed by joining
+this variable with the SHA2 checksum of the package file.
+
+If the mirror being used does not have the same checksum (*e.g.* with a
+pull-through cache like Artifactory), you can set the
+`PYTHON_BUILD_MIRROR_URL_SKIP_CHECKSUM` environment variable.
+
+If you don't have an SHA2 program installed, python-build will skip the download
+mirror and use official URLs instead. You can force python-build to bypass the
+mirror by setting the `PYTHON_BUILD_SKIP_MIRROR` environment variable.
+
+The official python-build download mirror is provided by
+[GitHub Pages](http://yyuu.github.io/pythons/).
+
+### Package download caching
+
+You can instruct python-build to keep a local cache of downloaded package files
+by setting the `PYTHON_BUILD_CACHE_PATH` environment variable. When set, package
+files will be kept in this directory after the first successful download and
+reused by subsequent invocations of `python-build` and `pyenv install`.
+
+The `pyenv install` command defaults this path to `~/.pyenv/cache`, so in most
+cases you can enable download caching simply by creating that directory.
+
+### Keeping the build directory after installation
+
+Both `python-build` and `pyenv install` accept the `-k` or `--keep` flag, which
+tells python-build to keep the downloaded source after installation. This can be
+useful if you need to use `gdb` and `memprof` with Python.
+
+Source code will be kept in a parallel directory tree `~/.pyenv/sources` when
+using `--keep` with the `pyenv install` command. You should specify the
+location of the source code with the `PYTHON_BUILD_BUILD_PATH` environment
+variable when using `--keep` with `python-build`.
+
+
+## Getting Help
+
+Please see the [pyenv wiki](https://github.com/pyenv/pyenv/wiki) for solutions to common problems.
+
+[wiki]: https://github.com/pyenv/pyenv/wiki
+
+If you can't find an answer on the wiki, open an issue on the [issue
+tracker](https://github.com/pyenv/pyenv/issues). Be sure to include
+the full build log for build failures.
+
+## Contributing
+
+### Testing new python versions
+
+If you are contributing a new python version for python-build,
+you can test the build in a [docker](https://www.docker.com/) container based on Ubuntu 18.04.
+
+With docker installed:
+
+```sh
+docker build -t my_container .
+docker run my_container pyenv install <my_version>
+```
+
+To enter a shell which will allow you to build and then test a python version,
+replace the second line with
+
+```sh
+docker run -it my_container
+```
+
+The container will need to be rebuilt whenever you change the repo,
+but after the first build, this will be very fast,
+as the layer including the build dependencies will be cached.
+
+Changes made inside the container will not be persisted.
+
+To test *all* new versions since a particular revision (e.g. `master`), `cd` to the root of your `pyenv` repo, and run this script:
+
+```sh
+set -e
+set -x
+
+docker build -t pyenv-test-container .
+
+git diff --name-only master \
+  | grep '^plugins/python-build/share/python-build/' \
+  | awk -F '/' '{print $NF}' \
+  | xargs -I _ docker run pyenv-test-container pyenv install _
+```
+
+- Build the docker image with the **t**ag pyenv-test-container
+- Look for the names files changed since revision `master`
+- Filter out any which don't live where python-build keeps its build scripts
+- Look only at the file name (i.e. the python version name)
+- Run a new docker container for each, building that version
