 ### Activate virtualenv
 
-Some external tools (e.g. [jedi](https://github.com/davidhalter/jedi)) might require you to `activate` the virtualenv.
-The `pyenv-virtualenv` will automatically activate/deactivate the virtualenv if the `eval "$(pyenv virtualenv-init -)"` is properly configured in your shell.
+Some external tools (e.g. [jedi](https://github.com/davidhalter/jedi)) might
+require you to `activate` the virtualenv and `conda` environments.
 
-You can also activate and deactivate a pyenv virtualenv this way:
+`pyenv-virtualenv` will automatically activate/deactivate the virtualenv if
+the `eval "$(pyenv virtualenv-init -)"` is properly configured in your shell.
+
+You can also activate and deactivate a pyenv virtualenv manually:
+
+```sh
+pyenv activate <name>
+pyenv deactivate
+```
+
+
+### Delete existing virtualenv
+
+Removing the directory in `~/.pyenv/versions` will delete the virtualenv, or you can run:
+
+```sh
+pyenv uninstall my-virtual-env
+```
+
+
+### virtualenv and pyvenv
+
+There is a [venv](http://docs.python.org/3/library/venv.html) module available
+for CPython 3.3 and newer.
+It provides a command-line tool `pyvenv` which is the successor of `virtualenv`
+and distributed by default.
+
+`pyenv-virtualenv` uses `pyvenv` if it is available and the `virtualenv`
+command is not available.
+
+
+### Anaconda and Miniconda
+
+Because Anaconda and Miniconda may install standard commands (e.g. `curl`, `openssl`, `sqlite3`, etc.) into their prefix,
+we'd recommend you to install [pyenv-which-ext](https://github.com/yyuu/pyenv-which-ext).
+
+You can manage `conda` environments by `conda env` as same manner as standard Anaconda/Miniconda installations.
+To use those environments, you can use `pyenv activate` and `pyenv deactivate`.
+
+```
+(root)$ pyenv version
+miniconda3-3.9.1 (set by /home/yyuu/.pyenv/version)
+(root)$ 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
+(root)$ pyenv activate 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
+(myenv)$ python --version
+Python 3.4.3 :: Continuum Analytics, Inc.
+(myenv)$ pyenv deactivate
+discarding /home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv/bin from PATH
+```
+
+You can use version like `miniconda3-3.9.1/envs/myenv` to specify `conda` environment as a version in pyenv.
+
+```
+(root)$ pyenv version
+miniconda3-3.9.1 (set by /home/yyuu/.pyenv/version)
+(root)$ pyenv shell miniconda3-3.9.1/envs/myenv
+(myenv)$ which python
+/home/yyuu/.pyenv/versions/miniconda3-3.9.1/envs/myenv/bin/python
+```
 
-    pyenv activate <name>
-    pyenv deactivate

 ## Version History
 
+#### 20150719
+
+* Add support for `conda` environments created by Anaconda/Miniconda (#91)
+* Look up commands for original version as well if the environment is created with `--system-site-packages` (#62)
+* Add error message if the source version is not installed (#83)
+
+#### 20150526
+
+* Use `typeset -g` with `precmd_functions` (#75)
+* activate: display setup instructions only with `PYENV_VIRTUALENV_INIT=0` (#78)
+* Ignore failure of pyenv activate (#68)
+
+#### 20150119
+
+ * Ignore errors from `pyenv-version-name` since it might fail if there is configuration error (yyuu/pyenv#291)
+ * The _shell_ version set in `activate` should be unset in `deactivate` (#61)
+ * Anaconda has `activate` script nevertheless it is not a virtual environment (#65)
+
+#### 20141106
+
+ * Stop creating after `ensurepip` since it has done by `ensurepip` itself
+ * Suppress some useless warnings from `pyenv virtualenv-init`
+
+#### 20141012
+
+ * Fix warnings from `shellcheck` to improve support for POSIX sh (#40)
+ * Do not allow whitespace in `VIRTUALENV_NAME` (#44)
+ * Should not persist `PYENV_DEACTIVATE` after automatic deactivation (#47, #48)
+
+#### 20140705
+
+ * Display information on auto-(de)?activation
+ * Support manual (de)?activation with auto-activation enabled (#32, #34)
+ * Exit as error when (de)?activation failed
+ * Use https://bootstrap.pypa.io/ to install setuptools and pip
+ * Create backup of original virtualenv within `$(pyenv root)/versions` when `--upgrade`
+
 #### 20140615
 
  * Fix incompatibility issue of `pyenv activate` and `pyenv deactivate` (#26)
