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

+that provides a `pyenv virtualenv` command to create virtualenv 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

 ## Installation
 
@@ -12,15 +15,30 @@ on UNIX-like systems.
 Installing pyenv-virtualenv as a pyenv plugin will give you access to the
 `pyenv virtualenv` command.
 
-    $ mkdir -p ~/.pyenv/plugins
-    $ cd ~/.pyenv/plugins
-    $ git clone git://github.com/yyuu/pyenv-virtualenv.git
+    $ git clone git://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. From that directory, you
 can check out a specific release tag. To update pyenv-virtualenv, run `git
 pull` to download the latest changes.
 
+### 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
+installed, you will also be able to use the `pyenv virtualenv` command.
+
+*This is recommended method of installation if you installed pyenv
+ with Homebrew.*
+
+    brew install pyenv-virtualenv
+
+Or, if you would like to install the latest development release:
+
+    brew install --HEAD pyenv-virtualenv

 ## Usage
 
 ### Using `pyenv virtualenv` with pyenv
@@ -29,14 +47,76 @@ To create a virtualenv for the Python version use with pyenv, run
 `pyenv virtualenv` with tha exact name of the version you want to create
 virtualenv. For example,
 
-    $ pyenv virtualenv --distribute 2.7.3 venv27
+    $ pyenv virtualenv 2.7.5 venv27
 
 virtualenvs will be created into a directory of the same name
 under `~/.pyenv/versions`.
 
 
+### 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.
+
+    $ pyenv version
+    3.3.2 (set by /home/yyuu/.pyenv/version)
+    $ pyenv virtualenv venv33
+
+
+### List existing virtualenvs
+
+`pyenv virtualenvs` shows you the list of existing virtualenvs.
+
+    $ pyenv shell venv27
+    $ pyenv virtualenvs
+    * venv27 (created from /home/yyuu/.pyenv/versions/2.7.5)
+      venv33 (created from /home/yyuu/.pyenv/versions/3.3.2)
+
+
+### 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 desired
+  version of virtualenv. If the virtualenv has not been installed,
+  pyenv-virtualenv will try to install the given version of virtualenv.
+* `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.
+
+
 ## Version History
 
+#### 20131216
+
+ * Use latest release of setuptools and pip if the version not given via environment variables.
+
+#### 20130622
+
+ * Removed bundled `virtualenv.py` script. Now pyenv-virtualenv installs `virtualenv` package into source version and then use it.
+ * On Python 3.3+, use `pyvenv` as virtualenv command if `virtualenv` is not available.
+ * Install setuptools and pip into environments created by `pyvenv`.
+
+#### 20130614
+
+ * Add `pyenv virtualenvs` to list all virtualenv versions.
+ * *EXPERIMENTAL*: Add `--upgrade` option to re-create virtualenv with migrating packages
+
+#### 20130527
+
+ * Remove `python-virtualenv` which was no longer used.
+ * Change the installation path of the `virtualenv.py` script. (`./libexec` -> `./libexec/pyenv-virtualenv/${VIRTUALENV_VERSION}`)
+ * Download `virtualenv.py` if desired version has not been installed.
+
+#### 20130507
+
+ * Display virtualenv information in `--help` and `--version`
+ * Update virtualenv version; 1.8.4 -> 1.9.1
+
 #### 20130307
 
  * Rename the project; `s/python-virtualenv/pyenv-virtualenv/g`
