I can still see the Trello card for this (was supposed to be implemented in April), but there’s no “Documentation” panel on Trello anymore, so it doesn’t show up.
I opened this forum just to “complain” about the same thing.
The documentation is almost absent and I only found docs to implement the Steam module and it stops there.
I cant even figure out how to get a instance of FOnlineSubsystemSteam. Also how to initialize and use server APIs for things like Steamworks.
I really hope you guys start documenting this stuff because its a pain to work with.
