Do you mean directly using the [ActivityPub Plugin](https://meta.discourse.org/t/activitypub-plugin/266794)? If so, this is what you can currently federate:

### Can be federated between Discourse instances

1. _Public_ topics can be federated when
  - created in a specified Category or created with a specified tag

2. Replies on those topics can also be federated _in both directions_
  - this is super cool, but only works if both instances are public

3. Deletions of these will also be federated

### What _can’t_ currently be federated between instances:

1. edits aren’t federated
  - this includes wiki edits

2. old topics / replies can’t be federated
  - this can be quite a challenge for legacy content

We are currently exploring federation between the #pavilion tag here on [meta.discourse.org](http://meta.discourse.org) and [coop.pavilion.tech](https://coop.pavilion.tech), so hopefully you’ll be able to see this in action in a real world setting shortly.
