In devel we have "tut 3" about Nim's macros. There should be dedicated tutorials about the GC, memory management and async and the modules should link to the tutorials. I'm not sure that long walls of text in [https://nim-lang.org/docs/asyncdispatch.html](https://nim-lang.org/docs/asyncdispatch.html) really help as async is split over multiple modules and it's a complex topic.
Making the runnableExamples runnable in a browser is also something we can do.
