	run from within Jamf Pro Self Service. Useful for Help Desks to
	ask end users to run when troubleshooting.

INSTRUCTIONS

	1) Edit the "Run Additional Commands" section to choose a behavior
	   for the Enable Remote Support button. This button can do anything
	   you'd like. Three examples are provided:
	   
	   - open an application
	   - run a Jamf Pro policy
	   - email the computer information to your Help Desk
	   
	2) In Jamf Pro choose Settings (cog wheel) > Computer Mangement >
	   Scripts and create a new script. Copy this script in full to the
	   script body and save.
	3) Then choose Computers > Policies and create a new policy. Add
	   the script to the policy and enable it for Self Service.
	4) When an end user calls your Help Desk, the technician can instruct
	   him or her to open Self Service and run the script for trouble-
	   shooting.
