# 1. Download the script as XML
# 2. Identify the script name
# 3. Extract the script contents from the downloaded XML
# 4. Save the script to a specified directory

# your own values where appropriate:
#
# To store the Jamf Pro URL in the plist file:
# defaults write com.github.jamfpro-info jamfpro_url https://jamf.pro.server.goes.here:port_number_goes_here

# To store the account username in the plist file:
# defaults write com.github.jamfpro-info jamfpro_user account_username_goes_here
#
# To store the account password in the plist file:
# defaults write com.github.jamfpro-info jamfpro_password account_password_goes_here
#
# If the com.github.jamfpro-info.plist file is available, the script will read in the
# relevant information from the plist file.
