-
-### 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-virtualenv issues](https://github.com/pyenv/pyenv-virtualenv/issues). You should look in 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 other plugins.
-  * This repository is maintaining the `pyenv-virtualenv` plugin only. Please refrain from reporting issues of other plugins here.

- [ ] Platform information (e.g. Ubuntu Linux 20.04):
- [ ] OS architecture (e.g. amd64):
- [ ] pyenv version:
- [ ] pyenv-virtualenv version:
- [ ] Python version:
- [ ] virtualenv version (if installed):
- [ ] Please attach the debug log of a faulty Pyenv invocation as a gist
-  * If the problem happens in a Pyenv invocation, you can turn on debug logging by setting `PYENV_DEBUG=1`, e.g. `env PYENV_DEBUG=1 pyenv install -v 3.6.4`
-  * If the problem happens outside of a Pyenv invocation, get the debug log like this:
-     ```
-     # for Bash
-     export PS4='+(${BASH_SOURCE}:${LINENO}): ${FUNCNAME[0]:+${FUNCNAME[0]}(): }'
-     # for Zsh
-     export PS4='+(%x:%I): %N(%i): '
-
-     set -x

-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-virtualenv/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 `bin/pyenv-virtualenv`
-  * 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

 ## Installation

 ### Installing as a pyenv plugin

-This will install the latest development version of pyenv-virtualenv into
-the `$(pyenv root)/plugins/pyenv-virtualenv` directory.
+Installing pyenv-virtualenv as a pyenv plugin will give you access to the
+`pyenv virtualenv` command.

-**Important note:**  If you installed pyenv into a non-standard directory, make
-sure that you clone this repo into the 'plugins' directory of wherever you
-installed into.
+    $ git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
+    $ exec "$SHELL"
+
+This will install the latest development version of pyenv-virtualenv into
+the `~/.pyenv/plugins/pyenv-virtualenv` directory. 
+**Important note:**  If you installed pyenv into a non-standard directory, make sure that you clone this
+repo into the 'plugins' directory of wherever you installed into.

 From inside that directory you can:
 - Check out a specific release tag. 
- - Get the latest development release by running `git pull` to download the
-   latest changes.
+ - Get the latest development release by running `git pull` to download the latest changes.

-💡 **WSL note:** If you're using WSL, we recommend setting Git to use Unix-style line endings to prevent script execution errors:
+### Installing with Homebrew (for OS X users)

-```sh
-git config --global core.autocrlf input
-```
-
-1. **Check out pyenv-virtualenv into plugin directory**
-
-    ```bash
-    git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv
-    ```
-
-    For the Fish shell:
-
-    ```fish
-    git clone https://github.com/pyenv/pyenv-virtualenv.git (pyenv root)/plugins/pyenv-virtualenv
-    ```
-
-2. (OPTIONAL) **Add `pyenv virtualenv-init` to your shell** to enable auto-activation of virtualenvs. This is entirely optional but pretty useful. See "Activate virtualenv" below.
-
-    ```bash
-    echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bashrc
-    ```
-
-    **Fish shell note**:  Add this to your `~/.config/fish/config.fish`
-

+[Homebrew](http://brew.sh) package manager. This
+will give you access to the `pyenv-virtualenv` command. If you have pyenv
 installed, you will also be able to use the `pyenv virtualenv` command.

 Or, if you would like to install the latest development release:

-```sh
-brew install --HEAD pyenv-virtualenv
-```
-
-After installation, you'll still need to do

-then add 
-```sh
-eval "$(pyenv virtualenv-init -)"

 ## Usage

 ### Using `pyenv virtualenv` with pyenv

-To create a virtualenv for the Python version used with pyenv, run
+To create a virtualenv for the Python version use with pyenv, run
 `pyenv virtualenv`, specifying the Python version you want and the name
 of the virtualenv directory. For example,

-```sh
-pyenv virtualenv 2.7.10 my-virtual-env-2.7.10
-```
+    $ pyenv virtualenv 2.7.6 my-virtual-env-2.7.6

-will create a virtualenv based on Python 2.7.10 under `$(pyenv root)/versions` in a
-folder called `my-virtual-env-2.7.10`.
+will create a virtualenv based on Python 2.7.6
+under `~/.pyenv/versions` in a folder called `my-virtual-env-2.7.6`. 

-`pyenv virtualenv` forwards any options to the underlying command that actually
-creates the virtual environment (`conda`, `virtualenv`, or `python -m venv`).
-See the output of `pyenv virtualenv --help` for details.

 ### Create virtualenv from current version

-If there is only one argument given to `pyenv virtualenv`, the virtualenv will
-be created with the given name based on the current pyenv Python version.
+If there is only one argument is given to `pyenv virtualenv`,
+virtualenv will be created with given name based on current
+version.

-```sh
-$ pyenv version
-3.4.3 (set by /home/yyuu/.pyenv/version)
-$ pyenv virtualenv venv34
-```
+    $ pyenv version
+    3.3.3 (set by /home/yyuu/.pyenv/version)
+    $ pyenv virtualenv venv33


 ### List existing virtualenvs

-`pyenv virtualenvs` shows you the list of existing virtualenvs and `conda` environments.
+`pyenv virtualenvs` shows you the list of existing virtualenvs.

-```sh
-$ pyenv shell venv34
-$ pyenv virtualenvs
-  miniconda3-3.9.1 (created from /home/yyuu/.pyenv/versions/miniconda3-3.9.1)
-  miniconda3-3.9.1/envs/myenv (created from /home/yyuu/.pyenv/versions/miniconda3-3.9.1)
-  2.7.10/envs/my-virtual-env-2.7.10 (created from /home/yyuu/.pyenv/versions/2.7.10)
-  3.4.3/envs/venv34 (created from /home/yyuu/.pyenv/versions/3.4.3)
-  my-virtual-env-2.7.10 (created from /home/yyuu/.pyenv/versions/2.7.10)
-* venv34 (created from /home/yyuu/.pyenv/versions/3.4.3)
-```
-
-There are two entries for each virtualenv, and the shorter one is just a symlink.
+    $ pyenv shell venv27
+    $ pyenv virtualenvs
+    * venv27 (created from /home/yyuu/.pyenv/versions/2.7.6)
+      venv33 (created from /home/yyuu/.pyenv/versions/3.3.3)


 ### Activate virtualenv

-Some external tools (e.g. [jedi](https://github.com/davidhalter/jedi)) might
-require you to `activate` the virtualenv and `conda` environments.
+Some external tools (e.g. [jedi](https://github.com/davidhalter/jedi)) might require you to `activate` the virtualenv.
+`pyenv activate` lets you to activate the virtualenv into your shell.

-If `eval "$(pyenv virtualenv-init -)"` is configured in your shell, `pyenv-virtualenv` will automatically activate/deactivate virtualenvs on entering/leaving directories which contain a `.python-version` file that contains the name of a valid virtual environment as shown in the output of `pyenv virtualenvs` (e.g., `venv34` or `3.4.3/envs/venv34` in example above) . `.python-version` files are used by pyenv to denote local Python versions and can be created and deleted with the [`pyenv local`](https://github.com/pyenv/pyenv/blob/master/COMMANDS.md#pyenv-local) command.
+    $ pyenv activate venv27

-You can also activate and deactivate a pyenv virtualenv manually:
+`pyenv activate` acts almost like following commands.
+The activate'd virtualenv will be persisted as _shell_ version.

-```sh
-pyenv activate <name>
-pyenv deactivate
-```
+    $ pyenv shell venv27
+    $ source "$(pyenv prefix venv27)/bin/activate"

+### Deactivate virtualenv

-### Delete existing virtualenv
+You can `deactivate` the activate'd virtualenv by `pyenv deactivate`.

-Removing the directories in `$(pyenv root)/versions` and `$(pyenv root)/versions/{version}/envs` will delete the virtualenv, or you can run:
+    $ pyenv deactivate

-```sh
-pyenv uninstall my-virtual-env
-```
+Or, there is an alias in `activate` command.
+This is prepared for similality between other `pyenv` commands like `shell` and `local`.

-You can also delete existing virtualenvs by using `virtualenv-delete` command, e.g. you can run:
-```sh
-pyenv virtualenv-delete my-virtual-env
-```
-This will delete virtualenv called `my-virtual-env`.
+    $ pyenv activate --unset

+`pyenv deactivate` acts almost like following commands.
+You can also use virtualenv's `deactivate` in place of `pyenv deactivate`,
+but be careful with the _shell_ version because it will be persisted even if `deactivate` has invoked.

-### virtualenv and venv
-
-There is a [venv](http://docs.python.org/3/library/venv.html) module available
-for CPython 3.3 and newer.
-It provides an executable module `venv` which is the successor of `virtualenv`
-and distributed by default.
-
-`pyenv-virtualenv` uses `python -m venv` if it is available and the `virtualenv`
-command is not available.
-
-
-### Anaconda and Miniconda
-
-You can manage `conda` environments by `conda create` as same manner as standard Anaconda/Miniconda installations.
-To use those environments, you can use `pyenv activate` and `pyenv deactivate`.
-
-```sh
-$ pyenv version
-miniconda3-3.9.1 (set by /home/yyuu/.pyenv/version)
-$ conda env list
-# conda environments:
-#
-myenv                    /home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv
-root                  *  /home/yyuu/.pyenv/versions/miniconda3-3.9.1
-$ pyenv activate miniconda3-3.9.1/envs/myenv
-discarding /home/yyuu/.pyenv/versions/miniconda3-3.9.1/bin from PATH
-prepending /home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv/bin to PATH
-$ python --version
-Python 3.4.3 :: Continuum Analytics, Inc.
-$ pyenv deactivate
-discarding /home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv/bin from PATH
-```
-
-If `conda` is available, `pyenv virtualenv` will use it to create environment by `conda create`.
-
-```sh
-$ pyenv version
-miniconda3-3.9.1 (set by /home/yyuu/.pyenv/version)
-$ pyenv virtualenv myenv2
-$ conda env list
-# conda environments:
-#
-myenv                    /home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv
-myenv                    /home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv2
-root                  *  /home/yyuu/.pyenv/versions/miniconda3-3.9.1
-```
-
-You can use version like `miniconda3-3.9.1/envs/myenv` to specify `conda` environment as a version in pyenv.
-
-```sh
-$ pyenv version
-miniconda3-3.9.1 (set by /home/yyuu/.pyenv/version)
-$ pyenv shell miniconda3-3.9.1/envs/myenv
-$ which python
-/home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv/bin/python
-```
-
+    $ deactivate
+    $ pyenv shell --unset

 ### Special environment variables

+You can set certain environment variables to control the pyenv-virtualenv.

 * `PYENV_VIRTUALENV_CACHE_PATH`, if set, specifies a directory to use for
  caching downloaded package files.
-* `VIRTUALENV_VERSION`, if set, forces pyenv-virtualenv to install the desired
-  version of virtualenv. If `virtualenv` has not been installed,
+* `VIRTUALENV_VERSION`, if set, forces pyenv-virtualenv to install desired
+  version of virtualenv. If the virtualenv has not been installed,
  pyenv-virtualenv will try to install the given version of virtualenv.
-* `GET_PIP`, if set and `venv` is preferred over `virtualenv`,
-  use `get_pip.py` from the specified location.
-* `GET_PIP_URL`, if set and `venv` is preferred over
-  `virtualenv`, download `get_pip.py` from the specified URL.
-* `PIP_VERSION`, if set and `venv` is preferred
-  over `virtualenv`, install the specified version of pip.
-* `PYENV_VIRTUALENV_VERBOSE_ACTIVATE`, if set, shows some verbose outputs on activation and deactivation
-* `PYENV_VIRTUALENV_PROMPT`, if set, allows users to customize how `pyenv-virtualenv` modifies their shell prompt. The default prompt ("(venv)") is overwritten with any user-specified text. Specify the location of the virtual environment name with the string `{venv}`. For example, the default prompt string would be `({venv})`.
+* `EZ_SETUP` and `GET_PIP`, if set and pyvenv is preferred than virtualenv,
+  use `ez_setup.py` and `get_pip.py` at specified location.
+* `EZ_SETUP_URL` and `GET_PIP_URL`, if set and pyvenv is preferred
+  than virtualenv, download `ez_setup.py` and `get_pip.py` from specified URL.
+* `SETUPTOOLS_VERSION` and `PIP_VERSION`, if set and pyvenv is preferred
+  than virtualenv, install specified version of setuptools and pip.
