No problem, happy to help get it right and learn.
When you do "git status" on the master branch it will tel you "you are X
number of commits ahead of origin/master and Y number of commits behind
origin/master" (may be other way around, did it from memory). This just means
that you start differing from what origin/master has X commits ago and there
are Y more commits beyond that point in origin/master.
So you will do "git reset HEAD~X" where X is the number of commits you are
ahead. This will bring you back to a common point with origin/master but leave
the changes that were made as unstaged/uncommitted changes.
After performing the steps you should be at a point where it says (when
running "git status") "you are 1 commit ahead of master". This 1 commit should
have all the changes you made for the Datadog implementation (and only those
changes).
The "reflog" is a history of all the git commands you do. So if you get too
mixed up, you can use reflog to rewind back to a certain command (ie. before
you started everything).
