+## Deploying
+
+ * Create a fat jar with `sbt assembly` and call it `Bot.jar`
+ * On the server, create a directory for your bot. Copy `docker-compose.yml` into it, create `data/bot/`, and copy `Bot.jar` into `data/bot/`
+ * Run `docker-compose up -d`
+
+You can view logs with `docker-compose logs`, take down the server with `docker-compose down`, and restart it with `docker-compose restart`.
