UnrealScript Documentation

Hello there.
Very interested in learning UnrealScript, but unfortunately when I started digging deeper I came across that the sections I needed were not available, could you please bring them back, or is there a backup somewhere?
Interested in the UnrealScript inner system, for example:

I’m not sure where you found those links, but it seems the documentation is still up: UDK | UnrealScriptHome

Edit: Oh, yes I see some sections lead to 404’s. Hopefully Epic can take note and get these pages back up…
