Hypothesis

If we... [do a thing]
Then... [this will happen]

Proposal

Update our user guidance to add instructions for how to use helm to rollback a release. This is a common support request, but is something that users should be able to do themselves. We can use details/instructions that we have sent to users previously when responding to support requests. See links below for examples:
