+## More words
+
+The full list of available commands:
+
+```
+     make build        - Build image lairdm/psortb
+     make push         - Push lairdm/psortb to public docker repo
+     make run          - Run psortb container
+     make start        - Start the EXISTING psortb container
+     make stop         - Stop psortb container
+     make restart      - Stop and start psortb container
+     make remove       - Stop and remove psortb container
+     make state        - View state psortb container
+     make logs         - View logs in real time
+```
+
+The Docker image exposes port 80, if this doesn't work for you, rather than "make run" you can manually start up the image using a different port.
+
+```bash
+    $ docker run -d -p 8000:80 --restart=always --name psortb lairdm/psortb:1.0.0
+```
