 5. Use automation: GitHub Projects includes automation features that can help you save time and streamline much of the organizational process. For example, you can set up rules to automatically move cards between columns based on certain criteria, such as when a task is assigned or when a label is added.  One cool feature is being able to automatically add items to your Project based on criteria like item type, label, status of the item, etc so your Project will always be reflective of the work going on in your repo/organization.  These can be enabled/disabled within each Project.
