Choose the pulse on any board that you would like to link to other.
In this example, we are choosing Project D to link to Project E.
Click Project D and it will open up.
Choose the @symbol and the name of the pulse - Project E.
Click Post and now you may click back and forth between projects!
**NOTE: There are no dependencies with dapulse just yet, so what you amend to one pule does not affect the other.
