Any further user instructions available?

Hello experts,
I read the membership use instructions, and at the end, it says "With your new Ping setup, you'll now be able to utilize that Ping when creating and editing Subscription Plans and Access Levels. "

Can you elaborate a bit more what that means? What is Ping used for here, can you please give me an example? How to utilize that Ping when creating and editing Subscription Plans and Access Levels?

Thank you very much
Ann
