This website is built using Docusaurus 2, a modern static website generator.
From the repo root:
$ yarn bootstrap
From packages/docs:
$ yarn build-contract-docs
The Markdown files generated by this command are tracked in version control. When you want to update the smart contract docs that are deployed on the docs site, you must run this command and commit the changes you want. We intentionally require this manual step, and do not execute this command as part of the "build" script, so that changes to the NatSpec comments in our smart contracts are not automatically deployed to the docs site. It wouldn't necessarily be appropriate to deploy such changes automatically, as they might describe contract behavior that has not yet been deployed to mainnet.
From packages/docs:
$ yarn start
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
From packages/docs:
$ yarn build
This command generates static content into the build directory and can be served using any static contents hosting service.
