# Documenting your project with wikis

You can use a wiki to share detailed, long-form information about your project.

## Links

* [About wikis](/en/communities/documenting-your-project-with-wikis/about-wikis)

  You can host documentation for your repository in a wiki, so that others can use and contribute to your project.

* [Adding or editing wiki pages](/en/communities/documenting-your-project-with-wikis/adding-or-editing-wiki-pages)

  You can add and edit wiki pages directly on GitHub or locally using the command line.

* [Creating a footer or sidebar for your wiki](/en/communities/documenting-your-project-with-wikis/creating-a-footer-or-sidebar-for-your-wiki)

  You can add a custom sidebar or footer to your wiki to provide readers with more contextual information.

* [Editing wiki content](/en/communities/documenting-your-project-with-wikis/editing-wiki-content)

  You can add images and links to content in your wiki, and use some supported MediaWiki formats.

* [Viewing a wiki's history of changes](/en/communities/documenting-your-project-with-wikis/viewing-a-wikis-history-of-changes)

  Because wikis are Git repositories, every change you make is a commit that you can view.

* [Changing access permissions for wikis](/en/communities/documenting-your-project-with-wikis/changing-access-permissions-for-wikis)

  Only repository collaborators can edit a public repository's wiki by default, but you can allow anyone with an account on GitHub.com to edit your wiki.

* [Disabling wikis](/en/communities/documenting-your-project-with-wikis/disabling-wikis)

  You can disable your repository's wiki.
