Help, essential modding tools?

[Zork]

So I want to start making some mods for rimworld and Basically what I am looking for is like a list of essential tools to have, such as for creating textures, coding, etc. any tools that can help to make a mod  (especially a mod for creating textures such as weapons and armor)

If your weapons and armor will be very "basic" as in not add any super strange effects that require higher modzardry

all you really, really need is a notepad and paint.net/ gimp/ photoshop/ Inkscape/ Illustrator/ other programs are available!

And then study the xml files of mods that add similar things! (That I found to be the easiest way! ofcourse it depends how you learn best but still! copying others till you understand how it all works does miracles! )
