Once you’ve signed up the the Yack beta you’ll receive a download link and activation code to enter into the app.
At this point you should go ahead and add the Feedback Yack community from the Browse Communities page.
Take a look at the #developers channel in the newly added Feedback community. This is your space to ask usage and implementation questions related to developing Yack Connectors.
Finally, enable Developer Mode from the app settings in the lower left-hand corner of the app.
