[complete and utter noob modder, how do I modify esp files]

If you like to watch tutorial videos, here's a link to a page's worth of them: Creation Kit Video Tutorials

 

If you prefer a hands on approach to learning things, you can always load up a mod that would do something similar to what you plan to do with XEdit and study what changes it makes, then make that kind of change with the Creation Kit. (Essentially reverse-engineer it) XEdit is also useful if you only want to tweak a mod to your liking, like changing the damage and weight of a weapon.

 

Other then that, you can look around in the Object Window for many items, actors, and other things in the game and study that itself. To me at least, looking through that is fairly straight-forward.

 

And one other suggestion, find your CreationKit.ini (in the Fallout 4 folder with the CreationKit.exe) and make these lines are like this, they will help avoid some problems before they appear:

bAllowMultipleMasterLoads=1

bAllowMultipleEditors=1

 

Edited for additional info.

Thanks

Ok I recently decided I wanted to do more than just download premade mods from someone else. However I soon ran into the problem that I have no idea of even where to start learning to mod. If it is not to much trouble, could someone please point me in the right direction? I have managed to download the creation kit but beyond that I have no idea.

I have the same problem octopuss, the main person i have found is irileth, at the part where you go to talk to balgruff in the second main questline mission. I have even tried console comands after reloading the save and making new saves failed. I would appreciate it if you could share any ways to fix this you find with me.
