revert to old commit in git code example

Example 1: how to revert a git revert

git revert <commitHashOfTheRevert> # locate the hash the revert was done 
                             #this will invert the changes made in that commit
                             #and preserve the git history

Example 2: reset to commit

# This will detach your HEAD, that is, leave you with no branch checked out:
git checkout 0d1d7fc32
