Documentation Revamps: Part 1 - The Division

[kamfretoz]

This PR attempts to revamp the documentations page.

For now it only splits the setup guide into its own dedicated sections instead of putting everything in one page.

Putting as draft for now as i'm still working on more improvements.

Feedbacks is highly appreciated!

Cloudflare build is no longer required, shouldn't be hard to merge once it's ready.
