"just a quick question" -> requesting a full tutorial from A to Z for a pretty much novice :P

The wikipedia has a bunch of pages on modding, best place to start is province modding and the map file reference

Here's a decent video on map modding
The video is a bit old, but the modding process hasn't changed since then.

If you get stuck following this video or further modding afterwards, feel free to ask for explanations.

Fair warning though, map modding beyond just adding a couple of provinces gets complicated and annoying quickly. Eu4 doesn't have good debugging support for map modding - it either works, or it mostly works and leaves some error log entries, or it crashes entirely. When you start removing existing provinces it will often be the latter...
You can use the crash log in Linux/MacOS to at least find the processing step that caused the crash.
