Create an account on the wiki, go to the #wiki channel on the Fabric Discord, and ping the Wiki Admin role with your wiki username and state that you request wiki editing access.

Example:

@Wiki Admin Username: Yourself

Hint: Please keep in mind, that the procedure is manual. Pinging once is the right approach.

Note: Wiki content written before these guidelines were added may not follow them. If appropriate it should be edited to do so.

1. When writing/updating a tutorial, put/update the Minecraft version in the topmost header (e.g. Adding Blocks (1.18.2))
2. Use <yarn> & <yarncode> tags to automatically update yarn mappings, rather than having to manually update them
3. The wiki is not a distribution system for useful mixins. If a mixin is useful enough to distribute, it's worth implementing it into a new or existing library mod. Distribution via wiki results in many variants across different mods, each with their own bugs and quirks. Packaging such a mixin as a library mod means bug fixes and improvements only need to be made once.

Search for the page name you want to create, when not found click on the link on:

…you can create or edit the page :a_new_page, named after your query.

or, just type the URL in your browser, for example to create a page named a_new_page under tutorial

https://fabricmc.net/wiki/tutorial:a_new_page?do=edit

You also probably want to add the new page to the tutorial sidebar, this is done by editing this page.

https://fabricmc.net/wiki/tutorial:sidebar

The sidebar for player tutorials is located here:

https://fabricmc.net/wiki/player:tutorials:sidebar

Each wiki page traverses the namespace upwards looking for a page name sidebar, and uses the first one it finds as a left side sidebar.

You can also find other sidebars using the sitemap link located in the top right.
