Git Tips[edit]

When you have changes in your working directory but want to put them aside for the time being, consider git stash. Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.
