+# Stash Everything
+
+Running the `git stash` command will take all the changes to tracked files
+in the working directory and stash them away. You can tack on the
+`--include-untracked` flag to make sure that untracked files are also
+included in the stash.
+
+You can take this a step further with the `--all` flag. This will stash
+everything included files that you've told git to ignore.
+
+You probably don't want to do this. I ran this command and realized after
+the command hung for about 10 seconds that I had just stashed the
+`node_modules` directory.
+
+See `man git-stash` for more details.
