RetroPie documentation is available at https://retropie.org.uk/docs/ - this wiki is no longer in use.

If you would like to contribute to the documentation, you can do so via the documentation repository at https://github.com/RetroPie/RetroPie-Docs/ (the documentation is in the subfolder docs)

The wiki/markdown contents which are used to generate the documentation have been moved to the repository above as it allows us more control over the changes and saves us from having to clean up bad edits and spam.
