TODOs:

• [x] Create a repo for the site https://github.com/lsd-rs/lsd-rs.github.io
• [ ] Choose a tool and theme with versions for the site, it should be better to fit both docs and themes(personally prefer using hugo)
• [ ] Create the docs site
• [ ] Create the theme site

It might also be helpful to copy the existing docs versioning disclaimer to directly above the config.yml snippet. Like others who have commented on other linked issues and PRs, I missed the text box when searching the readme. (And even once I read it, it didn't initially click that it applied to the configuration settings.) Having it appear alongside the config.yml sample would have been a big help, though.
