-Welcome to the pyenv wiki!
+pyenv is a tool for simple Python version management.
+
+To install pyenv, please refer to the [Readme][install].
+
+## Troubleshooting / FAQ
+
+### How is this better than pythonbrew and pythonz?
+
+See [[Why pyenv?]]
+
+### What is allowed in a `.python-version` file?
+
+The string read from a `.python-version` file must match the name of an existing
+directory in `~/.pyenv/versions/`. You can see the list of installed Python
+versions with `pyenv versions`.
+
+If you're using [python-build][], typically this will be one of [its Python version
+names][versions].
+
+Other version managers might allow fuzzy version matching on the string read
+from `.python-version` file, e.g. they might allow "3.3" (without patch suffix)
+to match the latest Python 3.3 release. **pyenv will not support this**, because
+such behavior is unpredictable and therefore harmful.
+
+### How to verify that I have set up pyenv correctly?
+
+1.  Check that `pyenv` is in your PATH:
+
+    ```sh
+    which pyenv
+    ```
+
+2.  Check that pyenv's shims directory is in PATH:
+
+    ```sh
+    echo $PATH | grep --color=auto "$(pyenv root)/shims"
+    ```
+
+    If not, see the [`pyenv init` step][init] in installation instructions.
+
+### pyenv is installed but things just aren't working for me!
+
+Please search [existing issues][issues] and open a new one if you can't find any answers. Here's a script that dumps information about your current environment; you can use [Gist][] to paste it online and share the URL to it in your bug report:
+
+```sh
+curl -s https://gist.github.com/mislav/4728286/raw/pyenv-doctor.sh | bash -x 2>&1
+```
+
+### Which shell startup file do I put pyenv config in?
+
+Typically it's one of the following:
+
+* bash: `~/.bash_profile`
+* zsh: `~/.zshrc`
+* ksh: `~/.kshrc`
+* other: `~/.profile`
+
+With bash on Ubuntu, you probably already have a `~/.profile`. In that case you
+should add pyenv config there instead of creating a `~/.bash_profile`. However,
+since this file is read only once per desktop login, you may achieve quicker
+results by adding pyenv to `~/.bashrc` instead.
+
+See [[Unix shell initialization]] for more info about how config files get
+loaded.
