How do I set up an automation where updating one board automatically updates another?

[beth.sutton]

I want to have it so that when I run an automation, the same card is created on both boards (a clone, I believe). I then want it so that when one of the cards is moved to 'Done' on one board, it automatically moves the card on the other board to 'Done'.

I think the use of Components would be good for you.
