Is there a Subscription Admin guide/help page?

Hello All---

I'm jumping into my company's Pendo usage post-implementation, and am looking to do some cleanup/management/monitoring of our subscription.

I'm wondering if there's documentation and/or a guide specific to Pendo Subscription Admins; in lieu of that--I primarily need to understand the process for, and impact of, deleting Pendo users from our subscription.

Looking forward to responses on this!
