Any best practices for documentation version control?

Hi folks! I'm trying to use Nextra to create documentation for a library, and it looks fully functional. The only thing I considered is how to deploy or organize multiple versions of documents. For example, like Node.js, which has versions such as v16.1, v16.8, v17, and many more. Users should be able to switch between these versions easily.
One thing that confuses me is whether I should deploy the website with multiple machines and split different versions using branches, or simply use the Next.js folder feature, such as creating a v1.0 folder and a v1.2 folder, to generate pages automatically. Both of them seem so hard to maintain.
