Documenting your project with wikis
You can use a wiki to share detailed, long-form information about your project.
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
You can add and edit wiki pages directly on GitHub or locally using the command line.
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
You can add images and links to content in your wiki, and use some supported MediaWiki formats.
Viewing a wiki's history of changes
Because wikis are Git repositories, every change you make is a commit that you can view.
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 your GitHub Enterprise Server instance to edit your wiki.
Disabling wikis
You can disable your repository's wiki.
