I got some commits in my repository:
like:
A - Added Feature A
B - Removed Feature B
C - Redesigned Feature C
D - Added Feature D
E - Added Feature
If you use TortoiseGit in Windows, you can right-click on the Git folder then click TortoiseGit > Show log. You can view all of the commits done before and then check the commit you'd want to revert to.
Click on the commit and you can see the changed files below. Click right on the files to be reverted and then click revert to parent revision.
