Aggregate app-specific FEDERATION.md documentation

[aschrijver]

(First posted to the Grassroots Fediverse discussion thread in this comment)

There is a convention for Fediverse Apps to document how they implemented ActivityPub federation. The convention involves adding a FEDERATION.md to the root of the app's codebase, so it is easy to keep up-to-date. A small number of apps are currently following this practice.

With the documentation decentralized like this, there's a bigger likelihood that the documentation is kept up-to-date.

At SocialHub we may investigate a better, more standardized documentation template for FEDERATION.md and maybe even create a FEP for the format.

I started the delightful project at Codeberg (which is similar to awesome-project at GH), and @[email protected] developed the delightful-club project that uses Codeberg CI to aggregate the various curated lists and compile them into the https://delightful.club website. The website auto-builds so that any changes in sub-lists are reflected on the site.

Similar mechanism might be used for fedidocs, based on FEDERATION.md docs it knows about.
