Onboarding checklists are the structures which contain the necessary actions that an end user needs to take, to start using the service effectively.
These could be the actions which must be taken or the actions that could be helpful for the end user to begin with.
The guides you create could easily be placed within these checklists and whenever a new user arrives to your platform, they can easily go over the checklist items to learn how to use your service quickly.
You can see a live example of onboarding checklist in our blog.
