-The `id` is a identifier for this addon, it has to be unique across
-all addons, as it is used to compare the addons with new ones from
-other sources to find updates. It is recomment to use something like
-"{author}-{title}". The `id` must be all lowercase and only contain
-characters of the set "[a-z][0-9]-", underscore is not allowed as it
-is used for the version number.
-
-The `version` number is a simple integer, it should be increased each
-time the addon is changed.
+[Information about add-on .nfo files](https://github.com/SuperTux/supertux/wiki/Add-ons#nfo-files)
 
-The `type` gives an indication of what is contained within the addon,
-valid values are "worldmap", "world", "levelset". At the moment this
-is only a description for the user and doesn't have any impact on how
-the addon is handled.
+## Adding an add-on
+Adding an add-on involves authoring two commits. Here is what each one has to add/change:
 
-The .nfo file itself needs to be stored in the top-level directory of
-the addon and should be named by the unique id of the addon, i.e.
-`/octo-levels.nfo` in this example.
-</details>
+1. Adds the archive of your add-on to the `repository/` directory.
+2. Edits the `index.nfo` for the latest SuperTux version, by adding the entry for your add-on. This will allow it to be downloaded from the in-game add-on manager.
 
-## Adding/Updating an addon
-To update an addon in the repository, you would need to submit a [pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests).
-The pull request should contain two commits:
-
-1. Adds/replaces the archive of your addon, contained in the `repository/` directory with a new one, which contains your changes.
-2. Edits the `index.nfo` for the latest SuperTux version, by adding/modifying the entry for your addon. This will allow it to be downloaded from the in-game addon manager.

-* **addon-commit-hash** represents the full commit hash of your first commit, which adds/replaces your addon in the `repository/` directory. This is important to include, because it allows the current SuperTux release to always get its versions of all addons for backwards compatibility.
-* **addon-md5-checksum** represents your new, modified addon archive's MD5 checksum hash. This needs to be updated every time the addon is updated, because the game will not be able to download your addon otherwise. The MD5 checksum is being used for checking the integrity of the addon.

+Add-ons are automatically updated in this repository. Updating the add-on archives in the `repository/` directory is all that has to be done by the user. The automatic workflow for updating add-ons in the latest index file will take care of the rest.
