================================================================================
Every time you edit the code,
it's bothering that you should do "add, writing commit message, commit"
Try to check help on "commit" by running
git commit --help
# ======================================================================
If you use -a[or -all] option on commit after you edit or remove a file,
"add" is automatically performed
git commit -a or
If you even want to write commit message in inline, first edit your file, and run
git commit -am "commit message"
