+Slackware notes
+===============
+Docker daemon starts and runs as root.
+To use the Docker command-line interface (the 'docker' program)
+as a non-root user, you must add yourself to the 'docker' group:
+  # gpasswd -a <your_username> docker
+... and then restart the Docker daemon:
+  # /etc/rc.d/rc.docker restart  
+You will have to logoff and login again if you added yourself to the group.
