Rot.js how to use it?

Hello Construct people,

I was checking the add-on section and discovered this one construct.net/en/make-games/addons/569/rotjs-updated but I don't exactly understand how to use it.

How to set the tilesets IDs to wall or floor? How do I place sprite (player, enemies, etc...) in the level generated? Is there a tutorial somewhere or documentation for beginners?

Thanks!
