+## Healthcheck

+This image contains [Dinnerbone's mcstatus](https://github.com/Dinnerbone/mcstatus) and uses
+its `ping` command to continually check on the container's. That can be observed
+from the `STATUS` column of `docker ps`
+
+```
+CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS                                 NAMES

+
+You can also query the container's health in a script friendly way:
+
+```
+> docker container inspect -f "{{.State.Health.Status}}" mc
+healthy
+```
+
+Finally, since `mcstatus` is on the `PATH` you can exec into the container
+and use mcstatus directly and invoke any of its other commands:
+
+```
+> docker exec mc mcstatus localhost status

 ## Running a Forge Server
 
 Enable Forge server mode by adding a `-e TYPE=FORGE` to your command-line.

+To use a pre-downloaded Forge installer, place it in the attached `/data` directory and

+        -e FORGE_INSTALLER_URL=http://HOST/forge-1.11.2-13.20.0.2228-installer.jar ...

+In both of the cases above, there is no need for the `VERSION` or `FORGEVERSION` variables.

 In order to add mods, you have two options.
