There has been a few discussions about tools to write documentation and tutorials in the past:
* [Love Nim but ...](https://forum.nim-lang.org/t/2364/2) with a link to a [nim to Sphinx extension](https://github.com/ziotom78/nimcfitsio/blob/master/docs/exts/nim-domain.py). * [Nim documentation - A Gitbook version](https://forum.nim-lang.org/t/2513#15629) with this [repo](https://github.com/euantorano/nim-docs) Was there some initiatives I missed? Both seem unmaintained.
