change the previous commit code example

Example 1: git command change to previous comit

git revert --no-commit 0766c053..HEAD
git commit


If you really do want to have individual commits 
(instead of reverting everything with one big commit), 
then you can pass --no-edit instead of --no-commit, 
so that you don't have to edit a commit 
message for each reversion. – user456814

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back
