Update documentation to reflect changes in service #64
Description
coding.blog is being repurposed: for now it'll just be a nice, free subdomain for anyone who wants to maintain an open source blog about coding. anyone can simply setup a blog on GitHub pages and register their subdomain, x.coding.blog, to that blog, by creating a PR to this repository and adding a config file to domain/list (see files there for example).
this change needs to be documented on the repo and on the codedoc pages. the old content perhaps should be archived, and I suspect it'd be nice to notify all who already have subdomains via email so that they can claim their blogs (this last one is a personal TODO for myself).
