100% agree! Was hoping to have the full manual done today, but it's not ready yet. Kinda worked out - I'll spend today ducking as the GitHub goliath whooshes over me for HN readership's attention ;-).

The rest of the product's docs are complete and full of screenshots:

so the git client will be too. This client animates changes to the DAG, so I'm experimenting with animated gifs so that the manual can capture the feel of using it.
