// a demo flag stream that toggles every 5 seconds
var toggle = false;
var gateStream = Observable.Interval(TimeSpan.FromSeconds(5))
    .Select(_ => toggle = !toggle);

# first get the merge commit hash
git log

# next get off master so you can play safe
git checkout -b RevertFeatureX

# revert the merge. Here "-m 1" says that the index 1 branch is the one to keep (hopefully this is the master/develop branch)
git revert -m 1 94d49c1d6edd3006208400b2de5920c4edff1db3

#This will then throw up a git file editor so you can enter in you commit message.
