There are 3 options available to customize for each step of your templates:
You can add a timeframe - a number of days. This can be handy to make sure that processes aren't slowing down too much. If a step isn't completed within a certain timeframe, it will show as Overdue in your dashbaord.
You can add instructions - this is the place to add in the program requirements or other info.
You can add an email notification: this will be automatically sent to either the applicant (the person who launched the process) or the template admins when the step is either started or completed, depending on the options you choose at setup.
