Hey, I've seen your deleted post about trying to seed your instance.
You seem to be the admin of a new instance.
By default, your instance won't see any remote communities content until someone subscribes.
Which is kind of a catch 22, because you kinda have to know about it to subscribe.
To browse for communities:
https://lemmyverse.net/communities
You can then use your instance's search bar to fetch it initially in order to subscribe to it yourself.
Which you've likely already done for this one.

There's also a tool that can do this for you:
https://lemmy-federate.com/ (which was formerly known as communityboost)
Then again it may subscribe to things you aren't interested in, so that may or may not be for you.

Cheers, welcome and good luck.
