 The sync server can easily be started using Docker.
 
+The first step is to `clone` the repository:
+
 ```bash
-wget https://raw.githubusercontent.com/streetwriters/notesnook-sync-server/master/docker-compose.yml
+git clone https://github.com/streetwriters/notesnook-sync-server.git
+
+# change directory
+cd notesnook-sync-server
 ```
 
 And then use Docker Compose to start the servers:
 
 ```bash
-docker compose up
+docker-compose up
 ```
 
 This takes care of setting up everything including MongoDB, Minio etc.
 
 ## TODO Self-hosting
 
-**Note: Self-hosting the Notesnook Sync Server is now possible, but without support. Documentation will be provided at a later date. We are working to enable full on-premise self-hosting, so stay tuned!**
