The lemmy-js-client docs have the HTTP Enpoints somewhere in there and if you click on “form” for a specific endpoint, it shows you the parameters.

Bigger problem is that nothing has any description, but all in all the docs are quite bad, even if complete.

Yeah, you just toot at the community (with a little bit of special form)

I had known Mastodon for quite some time but never used it until lots of people came over there from Twitter (which I had never used) and then I set up my own instance.

And now I’ve also set up my own Lemmy instance, I am still using Reddit aswell, but I hope Lemmy gets enough activity for it to be actually useful (seems to be on a good path).

(Yes, I don’t mix Mastodon and Lemmy, because Lemmy just works so different from most other ActivityPub software, it would just confuse me.)

Also I have used Matrix for quite a long time now.

Well yes, technically you can, but the two function very differently, I prefer having them seperate.

I run both my own Mastodon (social.jstsmthrgk.eu) and my own Lemmy (lemmy.jstsmthrgk.eu).

Mastodon is quite nice to host, even has a “single user instance” setting, also it has lots of users.
