Hi, Paul! I'm working on an event that runs throughout February, and they'd like to add Achievements for some custom post types (and/or post categories).
Obviously, the timing is a bit awkward! I can't find the documentation for the old versions, and the new version doesn't seem to have any yet.
Can you give me a hint on how to get started? I'm up to speed on CPTs and hooks; I just have no idea where to begin with Achievements.
