### Problem Right now the user documentation of mdbook is hosted on the github.io domain: https://rust-lang.github.io/mdBook/ I think it would be better to move it to be a subdomain of rust-lang.org, e.g. https://mdbook.rust-lang.org ### Proposed Solution In order to accomplish this one needs to [configure the DNS](https://docs.github.com/en/pages/configuring-a-custom-domain-for-your-github-pages-site/managing-a-custom-domain-for-your-github-pages-site) and in the repository of the project set the subdomain (and click on enforce https). The previous site will automatically redirect to the new one. What do you think? ### Notes [see also](https://users.rust-lang.org/t/better-branded-urls-for-rust-lang-projects/130888)
