-# Setting up Synapse Auto Invite Accept (optional)
+# Setting up Synapse Auto Invite Accept (optional, removed)
 
-The playbook can install and configure [synapse-auto-invite-accept](https://github.com/matrix-org/synapse-auto-accept-invite) for you.
+🪦 The playbook used to be able to install and configure [synapse-auto-invite-accept](https://github.com/matrix-org/synapse-auto-accept-invite), but no longer includes this component, as the same functionality [has been integrated](https://github.com/element-hq/synapse/pull/17147) to Synapse since [v1.109.0](https://github.com/element-hq/synapse/releases/tag/v1.109.0).
-
-In short, it automatically accepts room invites. You can specify that only 1:1 room invites are auto-accepted. Defaults to false if not specified.
-
-See the project's [documentation](https://github.com/matrix-org/synapse-auto-accept-invite/blob/main/README.md) to learn what it does and why it might be useful to you.
-
-**Note**: Synapse [v1.109.0](https://github.com/element-hq/synapse/releases/tag/v1.109.0), the same feature [has been merged](https://github.com/element-hq/synapse/pull/17147) into Synapse (see the [Native alternative](#native-alternative) section below). You'd better use the native feature, instead of the [synapse-auto-invite-accept](https://github.com/matrix-org/synapse-auto-accept-invite) 3rd party module.
-
-## Adjusting the playbook configuration
-
-If you decide that you'd like to let this playbook install the [synapse-auto-invite-accept](https://github.com/matrix-org/synapse-auto-accept-invite module for you, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
-
-```yaml
-matrix_synapse_ext_synapse_auto_accept_invite_enabled: true
-
-matrix_synapse_ext_synapse_auto_accept_invite_accept_invites_only_direct_messages: true
-```
-
-### Synapse worker deployments
-
-In a [workerized Synapse deployment](https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/c9a842147e09647c355799ca024d65a5de66b099/docs/configuring-playbook-synapse.md#load-balancing-with-workers) it is possible to run this module on a worker to reduce the load on the main process (Default is `null`). For example, add this to your configuration:
-
-```yaml
-matrix_synapse_ext_synapse_auto_accept_invite_worker_to_run_on: 'matrix-synapse-worker-generic-0'
-```
-
-There might be an [issue with federation](https://github.com/matrix-org/synapse-auto-accept-invite/issues/18).
 
 ## Native alternative
 
-Since Synapse [v1.109.0](https://github.com/element-hq/synapse/releases/tag/v1.109.0), the functionality provided by the [synapse-auto-invite-accept](https://github.com/matrix-org/synapse-auto-accept-invite) 3rd party module [has been made](https://github.com/element-hq/synapse/pull/17147) part of Synapse.
-
 Here's example configuration for using the **native** Synapse feature:
