+# git-sync
+
+A small CLI that implements the functionality of [`hub sync`](https://github.com/github/hub). Run `git-sync` to fast-forward outdated branches and remove merged and deleted upstream branches.
+
+### Why
+
+`hub` is deprecated by the [`gh` CLI](https://github.com/cli/cli), and I haven't found an alternative script that performs the same actions as `hub sync`.
+
+## Installation
+
+Either download from the [project releases](https://github.com/jacobwgillespie/git-sync/releases), or install with Homebrew:
+
+```shell
+$ brew install jacobwgillespie/tap/git-sync
+```
+
+## Usage
+
+Run either `git-sync` or `git sync`.
+
+## License
+
