Definitely the more information the merrier.
Perhaps GitHub's Wiki feature could be used??
As the resident crazy software freedom zealot, I of course continue to encourage the Nim community to be independent, "eat its own dogfood", avoid legalese, and not be dependent on sites like GitHub (now in the process of being swallowed be Microsoft, BTW), SO, Reddit, FreeNode, etc.
This may be a non-factor for 99% of developers, but that could change in the future. Even that 1% could give Nim a niche over competing programming language ecosystems.
This should go in our community page: https://nim-lang.org/community.html
There is already some guidelines there, feel free to improve it, the website is on github.
