This is the repo that hosts https://sorbet.run. We commit and push the Sorbet WASM payload to this repo on each master build of https://github.com/sorbet/sorbet.
Basically the entire site is in docs/.
If you are at all interested in making sorbet.run better, please contribute! We're happy to chat about potential improvements in the #internals on Slack (see https://sorbet.org/en/community).
