All - two things. 1) There's now a dev branch of openaps docs where you can target PRs moving forward. 2) we just merged my big re-org (#35 in docs) from dev to master . Will work with @channemann on resolving merge conflicts for his #36 that has some more improvements/edits (like a TOC so we aren't solely relying on a gitbook build for easy nav/seeing what's there). So if you are stuck/have been stuck and hadn't taken a look at dev in the past couple of days, master may help now (no more "blank page" for phase 3 & 4).
