Editing wiki content

In this article

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

Wikis are available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud and GitHub Enterprise Server.

You can create links in wikis using the standard markup supported by your page, or using MediaWiki syntax. For example:

  • If your pages are rendered with Markdown, the link syntax is [Link Text](full-URL-of-wiki-page).
  • With MediaWiki syntax, the link syntax is [[Link Text|nameofwikipage]].

Adding images

Wikis can display PNG, JPEG, and GIF images.

  1. On your GitHub Enterprise Server instance, navigate to the main page of the repository.

  2. Under your repository name, click Wiki.

  5. In the "Insert Image" dialog box, type the image URL and the alt text (which is used by search engines and screen readers).

  6. Click OK.

Linking to images in a repository

You can link to an image in a repository on GitHub Enterprise Server by copying the URL in your browser and using that as the path to the image. For example, embedding an image in your wiki using Markdown might look like this:

[[https://github.com/USERNAME/REPOSITORY/blob/main/img/octocat.png|alt=octocat]]

Supported MediaWiki formats

No matter which markup language your wiki page is written in, certain MediaWiki syntax will always be available to you.

  • Links (except AsciiDoc)
  • Horizontal rules via ---
  • Shorthand symbol entities (such as δ or €)

For security and performance reasons, some syntaxes are unsupported.

  • Transclusion
  • Definition lists
  • Indentation
  • Table of contents
