####very kind guide by imnotkind

#if you want to add a file :
git add <file>
#if you want to remove a file :
git rm <file>

##after you made changes :
#make sure to use git add <file> that you have newly added
git commit -a -m "message about change" (you can add -a if you didn't rm your deleted file)

#if you want to apply your change to server :
git push origin master

#if you want to make sure that the source is identical with the server or roll back :
git fetch --all
git reset --hard origin/master
git pull origin master
#ONLY SOURCE is in git, so don't forget to make clean, build again!

#if you want to establish the source to a particular commit state
git reset --hard <hash>

#if you want to ignore some file or folder, go to .git/info/exclude and add the name of it.
