### Adding links
|
|
|
|
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.
|
|
|
|
{% data reusables.repositories.navigate-to-repo %}
|
|
{% data reusables.repositories.sidebar-wiki %}
|
|
3. Using the wiki sidebar, navigate to the page you want to change, and then click **Edit**.
|
|
4. On the wiki toolbar, click **Image**.
|
|
|
|
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 {% data variables.product.product_name %} 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](https://github.com/gollum/gollum/commit/d1cf698b456cd6a35a54c6a8e7b41d3068acec3b))
|
|
- Horizontal rules via `---`
|
|
- Shorthand symbol entities (such as `δ` or `€`)
|
|
|
|
For security and performance reasons, some syntaxes are unsupported.
