+
+"""Displays and changes the current selected prime video card
+
+Left click will call 'sudo prime-select nvidia'
+Right click will call 'sudo prime-select nvidia'
+
+Running these commands without a password requires editing your sudoers file
+(always use visudo, it's very easy to make a mistake and get locked out of your computer!)
+
+sudo visudo -f /etc/sudoers.d/prime
+
+Then put a line like this in there:
+
+    user    ALL=(ALL) NOPASSWD: /usr/bin/prime-select
+
+If you can't figure out the sudoers thing, then don't worry, it's still really useful.
+
+Parameters:
+    * prime.nvidiastring: String to use when nvidia is selected (defaults to "intel")
+    * prime.intelstring: String to use when intel is selected (defaults to "intel")
+
+Requires the following executable:
+    * prime-select
