docs: add FAQ?

[gucio321]

Hi there, what about adding a special section of readme for frequently asked questions to avoid issues like: How to detect double-click event or how to open popup modal

Yeah, let's make it happen.

There are two things hover in my mind all the time:

1. How to write tests, increase the coverage and add giu to awesome go list.
2. Find a way to create a good code editor with syntax highlight (integrate with treesitter maybe...).

Please say something about style...

And examples on how to do specific things such as centering up, in the middle, down, on the sides, EVERYWHERE ! centering is weird for most people and I think having a cheat sheet with ready examples could help.

EDIT: spoke too fast
