• clone the original repo (https://github.com/splunk/splunkconf-backup) in your own github account (choose whatever repo name fits you)
• in your cloned repo, clic on "Settings" under the repo then "Secrets and Variables" then "Actions" then select "Variables"
• clic on "New Repository Variable" button (that appeared green on top right)
• name the variable TOPOLOGY
• write each instance name you wish to use (one per line)
• save the variable
• go to Actions menu on top then enable workflow actions
• got to settings for this repo under Actions/General , scrolldown to workflow permissions and change choice to Read and Write permissions, ave
• go back to actions
