PAWS pages need lots of documentation. https://tools.wmflabs.org/paws should give an overview of the project and some examples of what you can do. The next page should explain what will happen when you create a new server. The server main menu should include docs that explain what it means to create a new Python notebook, and so on.

@srodlund aptly directs to the documentation for jupyter. Which should contain most of the documentation that is needed for how to run jupyter. PAWS specific documentation can be found https://wikitech.wikimedia.org/wiki/PAWS
