Versions of docs and how to host previous versions

At present, we tag every version (including patch) in the repository but we only display three versions of the docs for the most recent minor versions in the versioned_docs folder. eg: 23.10.2, 23.7.3 and 23.4.1

In addition we also maintain the in flight development version in the docs folder.

In order to build or host a specific version eg 23.7.1

1. Clone this repo and checkout the tag

     git@github.com:hyperledger/besu-docs.git
     git checkout 23.7.1

1. Build and run locally

      yarn
      yarn run start
      Open up a browser tab and navigate to http://localhost:3000/development

1. (Optional) host this version on your own infrastructure (eg: nginx, s3 etc)
   

   yarn
   yarn run build
   # optional - this is to check the output locally
   yarn run serve 

          Host the contents of the `build` folder on your own infrastructure
