Nice one! We could even have the standard accountabilities 'slide' hidden at the start, and give it as a hint to let the participants self-correct a first round (depending on the situation)

Just added the reference to the Scrum Guide in the licence text of the new accountabilities card sets v2.1 in commit 8a8acbf

For the changes to the miro board this issue should still be checked/implemented
