Just post stuff. If someone finds it interesting, they'll comment on it, and before you know it, you'll have built a community. I just started one myself, not really stressing myself out over it :)

Home of the sh.itjust.works instance.
The recepy should be activity, time and patience. Dont give up, looking forward to see good posts on local 🐱
There are a few 'new community' communities that you can announce in. Lots of people are checking them right now:
if you have any questions about finding or subscribing to these federated communities, [email protected] has some good posts like this one: https://sh.itjust.works/post/124476
Keep contributing to it so it appears in All
It would be probably pretty similar if you just started a sub on reddit or any kind of forum I guess. It interest me in particular you community, but I'm not sure how it would be the best war to solve this in general, the newcommunities shared by @[email protected] seem like a great idea to advertise without annoying many people, probably will keep an eye on that.
It just occurred me how it was usually done in reddit, you could advertise in related subs, for example [email protected] but it's usually done with the permission of the mods of these subs.
