 ## Tips
+### Git Branching
+Each gist is a git repository. Although there are some limits on `git push`, like sub-directory. But guess what? Push another branch to `github.com` is allowed. So why not use this feature for your gist workflow?

+```
+# show list without hint
+hint=false gist

+# just print the repo path with a given index
+gist 3 --no-action
+
+# delete your third gist without confirmation
+confirm=false gist delete 3
