How do I mod the tutorial?

[Void Animates]

How do I edit the tutorial text? I'm just bored, and I want to do it for fun!
I might need it later on.

If im not wrong, you have to load the map file trough Slade, so you can go to edit the scripts it has, as all the text said on the tutorial gets stored in one of these files, which i cant rememer which it is exactly
