 Speaking of multiple servers, it's handy to give your containers explicit names using `--name`, such as
 
-    docker run -d -p 25565:25565 --name minecraft-vanilla itzg/minecraft-server
+    docker run -d -p 25565:25565 --name minecraft-default itzg/minecraft-server
 
 With that you can easily view the logs, stop, or re-start the container:
