Describe the solution you'd like
Some suggestions for what to add:

• a tutorial, get started, how to understand it. Can be pretty basic, like: start with nothing, add these files, this is what you get, add more files, now you get this.. etc.
• a basic how-to do common scenarios, like: base layout and partials. How to use this partials features to solve a particular problem.
• For both of the above: give actual example code.

Describe alternatives you've considered
We could create videos, but the quicker way would be written examples.
