If you don’t use custom fields, feel free to skip this section and come back to it later if you start using them. They’re quite helpful for advanced automation because as you’ll see, there are a lot of triggers for watching them!
When all custom fields are completed

Real-world example
When custom fields are completed, move the card to the Ready to Use list.
This rule is useful for creating a sort of “form validation” type of workflow that moves a card to the next stage when you have all the information ready...
