git checkout
git clone copies a repository from somewhere else
git commit commits changes currently staged
git config
git diff shows difference between current directory contents and what you have staged
git fetch fetches named heads or tags from one or more other repositories, along with the objects necessary to complete them.
git init initializes a new repository; does not add anything

git reset resets current HEAD to the specified state
git rm removes files from staging and also from the directory
git stash saves local modifications, reverts the working directory to match HEAD commit
git status shows status of current repository
