After bouncing around in the outdated ( (c) 2017) PB User’s Guide looking for how one gets one’s book from the authoring phase to making a coherent ePub file for IDPF validating, etc., I kept either not finding stuff or finding wrong stuff. So I’ve decided to use the PB-endorsed tool Hypothesis (an old friend in other venues) and opened a Pressbooks User’s Guide slate. It’s specific, so it’s private. But it shouldn’t be and anyone’s welcome by using the Hypo. login permission:

Have at it! And if you’re not “into” Hypothesis, then here’s your chance.
