 If you're looking for a simple way to deploy this to the Amazon Web Services Cloud, check out the [Minecraft Server Deployment (CloudFormation) repository](https://github.com/vatertime/minecraft-spot-pricing). This repository contains a CloudFormation template that will get you up and running in AWS in a matter of minutes. Optionally it uses Spot Pricing so the server is very cheap, and you can easily turn it off when not in use.
 
+### Using Docker Compose
+
+Rather than type the server options below, the port mappings above, etc
+every time you want to create new Minecraft server, you can now use
+[Docker Compose](https://docs.docker.com/compose/). Start with a
+`docker-compose.yml` file like the following:
+
+```yml
+version: "3"
+
+services:
+  mc:
+    image: itzg/minecraft-server
+    ports:
+      - 25565:25565
+    environment:
+      EULA: "TRUE"
+    tty: true
+    stdin_open: true
+    restart: unless-stopped
+```
+
+and in the same directory as that file run
+
+    docker-compose up -d
+
+Now, go play...or adjust the `environment` section to configure
+this server instance.
+
+## Troubleshooting
+
+To troubleshoot the container initialization, such as when server files are pre-downloaded, set the environment variable `DEBUG` to `true`. The container logs will include **much more** output, and it is highly recommended including that output when reporting any [issues](https://github.com/itzg/docker-minecraft-server/issues).
+
+To troubleshoot just the command-line used to start the Minecraft server, set the environment variable `DEBUG_EXEC` to `true`.
+
+To troubleshoot any issues with memory allocation reported by the JVM, set the environment variable `DEBUG_MEMORY` to `true`.

+> **NOTE:** Non-vanilla versions might have their own configuration file, you might have to disable their watchdogs separately. For PaperMC servers, you need to send the JVM flag `-Ddisable.watchdog=true`, this can be done with the docker env variable `-e JVM_DD_OPTS=disable.watchdog:true`
 
 On startup the `server.properties` file is checked and, if applicable, a warning is printed to the terminal. When the server is created (no data available in the persistent directory), the properties file is created with the Watchdog disabled.
