- Make default Node config force-overwrite its socket file
- puppet.sock -> rpc.sock

 1. Generate the appservice registration by running the container again, and update your homeserver configuration to accept it
 1. Run the bridge module with `docker run --restart unless-stopped -v $(pwd):/data:z matrix-appservice-kakaotalk`
     * Additionally, you should either add the bridge to the same Docker network as your homeserver and database with `--network=<name>` (when they are running in Docker), or expose the correct port(s) with `-p <port>:<port>` or `--network=host` (when they are running outside Docker).
+    * If the Node module is configured to use a unix socket, make sure to start the bridge module's container _after_ the Node module's container. Otherwise, the bridge module may not be able to find the socket file.
 
 ## Upgrading
 Simply `git pull` or `git rebase` the latest changes, rerun all `docker build` commands, then run new containers for the freshly-built images.
