 pyenv-virtualenv is a [pyenv](https://github.com/yyuu/pyenv) plugin

+that provides a `pyenv virtualenv` command to create virtualenvs for Python
 on UNIX-like systems.
 
 (NOTICE: If you are an existing user of [virtualenvwrapper](http://pypi.python.org/pypi/virtualenvwrapper)
 and you love it, [pyenv-virtualenvwrapper](https://github.com/yyuu/pyenv-virtualenvwrapper) may help you

+(additionally) to manage your virtualenvs.)
 
 ## Installation
 
 ### Installing as a pyenv plugin
 
-Installing pyenv-virtualenv as a pyenv plugin will give you access to the
-`pyenv virtualenv` command.
-
-    $ git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
-
 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.
+
+**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.
+
+1. **Check out pyenv-virtualenv into plugin directory**
+
+        $ git clone https://github.com/yyuu/pyenv-virtualenv.git ~/.pyenv/plugins/pyenv-virtualenv
+
+2. **Add `pyenv virtualenv-init` to your shell** to enable activation of virtualenv. This is entirely optional but pretty useful.
+
+        $ echo 'eval "$(pyenv virtualenv-init -)"' >> ~/.bash_profile
+    **Zsh note**: Modify your `~/.zshenv` file instead of `~/.bash_profile`.
+    **Pyenv note**: You may also need to add 'eval "$(pyenv init -)"' to your profile if you haven't done so already.
+
+3. **Restart your shell to enable pyenv-virtualenv**
+
+        $ exec "$SHELL"
+
 
 ### Installing with Homebrew (for OS X users)
 
 Mac OS X users can install pyenv-virtualenv with the
-[Homebrew](http://brew.sh) package manager. This
-will give you access to the `pyenv-virtualenv` command. If you have pyenv
+[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.
 
-*This is recommended method of installation if you installed pyenv
+*This is the recommended method of installation if you installed pyenv
  with Homebrew.*
 
-    brew install pyenv-virtualenv
+```
+$ brew install pyenv-virtualenv
+```
 
 Or, if you would like to install the latest development release:
 
-    brew install --HEAD pyenv-virtualenv
+```
+$ brew install --HEAD pyenv-virtualenv
+```
+
+After installation, you'll still need to add `eval "$(pyenv virtualenv-init
+-)"` to your profile (as stated in the caveats). You'll only ever have to do
+this once.
 
 
 ## Usage

-To create a virtualenv for the Python version use with pyenv, run
+To create a virtualenv for the Python version used with pyenv, run
 `pyenv virtualenv`, specifying the Python version you want and the name
 of the virtualenv directory. For example,
 
-    $ pyenv virtualenv 2.7.6 my-virtual-env-2.7.6
+```
+$ pyenv virtualenv 2.7.7 my-virtual-env-2.7.7
+```
 
-will create a virtualenv based on Python 2.7.6
-under `~/.pyenv/versions` in a folder called `my-virtual-env-2.7.6`. 
+will create a virtualenv based on Python 2.7.7 under `~/.pyenv/versions` in a
+folder called `my-virtual-env-2.7.7`.
 
 
 ### Create virtualenv from current version
 
-If there is only one argument is given to `pyenv virtualenv`,
-virtualenv will be created with given name based on 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.
 
-    $ pyenv version
-    3.3.3 (set by /home/yyuu/.pyenv/version)
-    $ pyenv virtualenv venv33
+```
+$ pyenv version
+3.4.2 (set by /home/yyuu/.pyenv/version)
+$ pyenv virtualenv venv34
+```
 
 
 ### List existing virtualenvs
 
-`pyenv virtualenvs` shows you the list of existing virtualenvs.
+`pyenv virtualenvs` shows you the list of existing virtualenvs:
 
-    $ 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)
+```
+$ pyenv shell venv27
+$ pyenv virtualenvs
+* venv27 (created from /home/yyuu/.pyenv/versions/2.7.7)
+  venv34 (created from /home/yyuu/.pyenv/versions/3.4.1)
+```
 
 
 ### Activate virtualenv
 
-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.
+Some external tools (e.g. [jedi](https://github.com/davidhalter/jedi)) might
+require you to `activate` the virtualenv.
 
-    $ pyenv activate venv27
+`pyenv-virtualenv` will automatically activate/deactivate the virtualenv if
+the `eval "$(pyenv virtualenv-init -)"` is properly configured in your shell.
 
-`pyenv activate` acts almost like following commands.
+You can also activate and deactivate a pyenv virtualenv manually:
 
-    $ pyenv shell venv27
-    $ source "$(pyenv prefix venv27)/bin/activate"
+    pyenv activate <name>
+    pyenv deactivate
 
-You can deactivate the activate'd virtualenv by `pyenv deactivate`.
 
-    $ pyenv deactivate
+### Delete existing virtualenv
+
+Removing the directory in `~/.pyenv/versions` will delete the virtualenv, or you can run:
+
+    pyenv uninstall my-virtual-env
+    
+
+### virtualenv and pyvenv
+
+There is a [venv](http://docs.python.jp/3/library/venv.html) module available
+for CPython 3.3 and newer.
+It provides a command-line tool `pyvenv` which is the successor of `virtualenv`
+and distributed by default.
+
+`pyenv-virtualenv` uses `pyvenv` if it is available and the `virtualenv`
+command is not available.
