I noticed that OpenComputers' manual are written in Markdown format, and docs can be added by external sources like ExtraCells2(see https://github.com/ExtraCells/ExtraCells2/tree/rv6-1.12/src/main/resources/assets/extracells/doc), so it should be possible and easy to add LostUser's README.md to OpenComputers' manual.

By doing so, I can view the docs without the needs of opening a browser page and switching back and forth, definitely will be a smoother gameplay

Very nice idea! Thank you for noticing me this. I will think to implement it.
