How to set up multiple checklists in sequential order

Sometimes, you'd like to have users learn a set of features before showing them advanced lessons. For example, there are two checklists, say A and B, and your users will only see B if the person completes A first.

To accomplish this, you can set up "Trigger" (which is run on a user after completing a checklist) in Checklist A to tag a user as “checklist-A-completed”.

Tag a user as “checklist-A-completed”

Then, in Checklist B, set up a filter that includes "User tag equals checklist-A-completed". This way a user will only see Checklist B after the person completes Checklist A.
