 * `TZ`: the [timezone](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) the container will run with. Defaults to `UTC`.
 
+For more complex setups (e.g. for workers) you can also pass your args directly to synapse using `run` mode. For example like this:
+
+```
+docker run -d --name synapse \
+    --mount type=volume,src=synapse-data,dst=/data \
+    -p 8008:8008 \
+    matrixdotorg/synapse:latest run \

+    --config-path=/data/homeserver.yaml \
+    --config-path=/data/generic_worker.yaml
+```
+
+If you do not provide `-m`, the value of the `SYNAPSE_WORKER` environment variable is used. If you do not provide at least one `--config-path` or `-c`, the value of the `SYNAPSE_CONFIG_PATH` environment variable is used instead.

 ## Generating an (admin) user
 
 After synapse is running, you may wish to create a user via `register_new_matrix_user`.
