##REBASE

* git rebase -i HEAD~4 OR HEAD^^^^ OR HEAD@{4}

all mean 4 prior to head

* git commit --ammend

    --ammend : when dropping an edit into a rebase, make changes, add them then ammend

* git rebase --continue

    --continue : finishes rebase, allows for editing of commit message

* git pull --rebase
