+# Script to install a small ruby based server.
+# - Creates a webserver user and group for running ruby in
+# - Uses bundler to handle dependancies
+# - Puma since webrick doesn't doesn't bind to both IPv4 and IPv6 at the
+#       same time due to a bug.
+# - Creates systemd unit file for puma based ruby server.
+# - Starts puma process when complete on port 9463
+# - PATH put in .bash_profile so ruby works in non interactive login shell.
+#
+# To start the webserver.
+#   systemctl start ruby_website
