+### Uninstalling pyenv
+
+The simplicity of pyenv makes it easy to temporarily disable it, or
+uninstall from the system.
+
+1. To **disable** pyenv managing your Python versions, simply remove the
+  `pyenv init` line from your shell startup configuration. This will
+  remove pyenv shims directory from PATH, and future invocations like
+  `python` will execute the system Python version, as before pyenv.
+
+  `pyenv` will still be accessible on the command line, but your Python
+  apps won't be affected by version switching.
+
+2. To completely **uninstall** pyenv, perform step (1) and then remove
+   its root directory. This will **delete all Python versions** that were
+   installed under `` `pyenv root`/versions/ `` directory:
+
+        rm -rf `pyenv root`
+
+   If you've installed pyenv using a package manager, as a final step
+   perform the pyenv package removal. For instance, for Homebrew:
+
+        brew uninstall pyenv

+
+You can affect how pyenv operates with the following settings:
+
+name | default | description
+-----|---------|------------
+`PYENV_VERSION` | | Specifies the Python version to be used.<br>Also see [`pyenv shell`](#pyenv-shell)
+`PYENV_ROOT` | `~/.pyenv` | Defines the directory under which Python versions and shims reside.<br>Also see `pyenv root`
+`PYENV_DEBUG` | | Outputs debug information.<br>Also as: `pyenv --debug <subcommand>`
+`PYENV_HOOK_PATH` | [_see wiki_][hooks] | Colon-separated list of paths searched for pyenv hooks.
+`PYENV_DIR` | `$PWD` | Directory to start searching for `.python-version` files.
