HINT: Index: Adding changes step by step

[CodeAsm]

DO NOT use git mv [original] [target name]
as this will add the rename to the cached files to be commited.

Us mv instead. or manually change the file name.

I learned to use git mv to rename or move files and this tripped me up in this level so much. i was looking into the sourcecode for any errors.
https://github.com/git-learning-game/oh-my-git/blob/main/levels/index/steps#L20
is the exact spot that confused me, what where they checking? well, changes, that are NOT yet been cached or commited:
$ git diff --name-only
returns 0, nada, if you add them, and git mv emediatly adds them to the cach and commits the changes when you do a single commit (like git add broken_bottle, it ALSO adds the other renamed files if u use git mv)

TLDR:
use MV, not GIT MV like i did
