Guides to ActivityPub

ActivityPub is a standard that allows different web applications to interact so that users can pool their information and collaborate across instances (websites, applications), even ones running different softwares.

As a relatively new standard, ActivityPub is not yet super well documented either for adopters or for developers. To help address that, in January 2020 we undertook a project to produce ActivityPub documentation guides. Steps included:

• Reached out to individuals active in the ActivityPub space.
• Researched ActivityPub implementations.
• Compiled links to implementations and existing documentation.
• Wrote a set of three guides:
  • Introduction to ActivityPub–for everyone!
  • Guide for ActivityPub users
  • Guide for ActivityPub implementers

The results are some of the best sources for getting up to speed quickly on ActivityPub and how it helps enable the Fediverse.
