Documentation Refactoring

[ElectronicsArchiver]

Please check the Preview.

This is a draft PR, just so you notice it. I would love to merge it already, despite not everything being finished yet, just to have most of the work included already. If you approve, I would switch it to non-draft.

Questions

• Is there any need to keep the 'execute with su' instructions? Can't they all be replaced with sudo?
