You could try running through <https://narimiran.github.io/nim-basics>/ or @Stefan_Salweski Nim Programming book. And then with that knowledge go through Nim Days: <https://xmonader.github.io/nimdays>/
This should give a beginner a stable foundation and enough projects to build and tinker with. There is currently no resource that I know of that combines both for beginners, they are very hard and time consuming to make :(.
