 The TURN Server is a VoIP media traffic NAT traversal server
 and gateway. It can be used as a general-purpose network
 traffic TURN server and gateway, too.
+
+You need the 'turnserver' group and user to run this script,
+for example:
+
+  groupadd -g 366 turnserver
+  useradd -u 366 -g turnserver -d /var/lib/turn -s /bin/bash turnserver
+
+If you wish another group and username, you can set TURN_GROUP and TURN_USER,
+for example:
+
+  TURN_GROUP=mygroup TURN_USER=myuser ./coturn.SlackBuild
