If you want to cut a new versioned documentation release, delete everything in the Dockerfile after WORKDIR /app/website, then from this directory:

docker build --no-cache -f docusaurus/Dockerfile -t docusaurus-doc .
docker run -it -p3000:3000 -v $(pwd)/docusaurus:/app/website -v $(pwd)/readmes:/app/docs docusaurus-doc bash

Inside the container,

yarn install
yarn build

Then you can use yarn commands to create a new versioned release.
