Federation is *not set up* by default. You can add this [this federation block](https://github.com/lemmynet/lemmy/blob/main/config/config.hjson#L64) to your `lemmy.hjson`, and ask other servers to add you to their allowlist.

# Federation
Lemmy has three types of federation:
- Allowlist: Explicitly list instances to connect to.
- BlockList: Explicitly list instances to not connect to. Federation is open to all other instances.
- Open: Federate with all potential instances.
- Strict Allowlist: Only federate with allowlist, and block everything else.
**Federation is not set up by default.** You can add this [this federation block](https://github.com/lemmynet/lemmy/blob/main/config/config.hjson#L64) to your `lemmy.hjson`, and ask other servers to add you to their allowlist.
Lemmy uses the ActivityPub protocol (a W3C standard) to enable federation between different servers (often called instances). This is very similar to the way email works. For example, if you use gmail.com, then you can not only send mails to other gmail.com users, but also to yahoo.com, yandex.ru and so on. Email uses the SMTP protocol to achieve this, so you can think of ActivityPub as "SMTP for social media". The amount of different actions possible on social media (post, comment, like, share, etc) means that ActivityPub is much more complicated than SMTP.
As with email, ActivityPub federation happens only between servers. So if you are registered on `enterprise.lemmy.ml`, you only connect to the API of `enterprise.lemmy.ml`, while the server takes care of sending and receiving data from other instances (eg `voyager.lemmy.ml`). The great advantage of this approach is that the average user doesn't have to do anything to use federation. In fact if you are using Lemmy, you are likely already using it. One way to confirm is by going to a community or user profile. If you are on `enterprise.lemmy.ml` and you see a user like `@nutomic@voyager.lemmy.ml`, or a community like `!main@ds9.lemmy.ml`, then those are federated, meaning they use a different instance from yours.

Follow the normal installation instructions, either with [Ansible](../administration/install_ansible.md) or
[manually](../administration/install_docker.md). Then replace the line `image: dessalines/lemmy:v0.x.x` in
`/lemmy/docker-compose.yml` with `image: dessalines/lemmy:federation`. Also add the following in
`/lemmy/lemmy.hjson`:
```
federation: {
enabled: true
tls_enabled: true,
allowed_instances: example.com,
}
```
`/lemmy/docker-compose.yml` with `image: dessalines/lemmy:federation`. Add and configure [this federation block](https://github.com/lemmynet/lemmy/blob/main/config/config.hjson#L64) to your `lemmy.hjson`.
Afterwards, and whenever you want to update to the latest version, run these commands on the server:
