I want to know how to use the Antenna feature of Firefish to customize my feed and see more relevant content based on the topics I like, how to follow lemmy communities, how to post on lemmy and vote posts/comments on lemmy from there. Is there a documentation where I can learn about that?

I would like to be able to choose how much I want to see of the topics I like. What platform offers something similar to Bluesky customizable feeds but in the fediverse?
