Nice tutorial. I do advise to not use the repo folder for mods you created yourself. If you click on "Delete all repo mods" it will get deleted. You can put the zip just in /mods or you can unpack it into /mods/unpacked and use the game to repack
Thanks! I added a note concerning the mods and mods/repo folders. Feedback like this is really useful and if you have time, don't hesitate to proof watch and comment on my future tutorials!
