+# A basic cli for handling the staging with git
+#
+# This is a simple cli that utilizes the output from several git commands, and
+# pipes them into `gum filter` and `gum choose` to provide a simple cli wrapper
+# for `git add` and `git reset`.
+#
+# For a more feature complete version of this script check out
+# [Nickiel12's Git-Gum](https://github.com/Nickiel12/Git-Gum).
