• Discard all history and changes back to the specified commit:
  $ git reset --hard [commit]

Group Changes

• List all local branches in the current repository:
  $ git branch

• Create a new branch with specified name:
  $ git branch [branch-new]

• Switch to the specified branch and updates the working directory:
  $ git checkout [branch-name]

• Combine the specified branch to the current branch:
  $ git merge [branch-name]

• Delete the specified branch:
  $ git branch -d [branch-name]

Configure
