ProseMirror for dummies

This repo used to be a simple cookbook but I decided to convert this repo into "ProseMirror for dummies". In part because I wil most likely forget all the info written here, and in part because I'd like to help you, dear reader, in your struggle to use this library which is not for the faint of heart.

This is a work in progress. If you have any suggestion, please do not hesitate to create an issue or a PR.

Also, check the ProseMirror Utils repo by Atlassian. Not only it is useful per se, but the source code offers a lot of information on how to to certain things.
