+### Media worker
+
+The media worker is slightly different than the generic one. It doesn't use the
+`synapse.app.generic_worker`, but a specialised one: `synapse.app.media_repository`.
+To prevent the main process from handling media itself, you have to explicitly
+tell it to leave that to the worker, by adding this to the configuration (in
+our setup `conf.d/listeners.yaml`):
+
+```
+enable_media_repo: false
+media_instance_running_background_jobs: mediaworker
+```
+
+The worker `mediaworker` looks like this:
+
+```
+worker_app: "synapse.app.media_repository"
+worker_name: "mediaworker"
+worker_log_config: "/etc/matrix-synapse/logconf.d/media.yaml"

+If you use more than one mediaworker, know that they must all run on the same
