The README says to add [sindresourhus/LaunchAtLogin](https://github.com/sindresorhus/LaunchAtLogin) in the Swift Package Manager. When we open the [sindresourhus/LaunchAtLogin](https://github.com/sindresorhus/LaunchAtLogin) repository, it redirects us to [sindresourhus/LaunchAtLogin-Legacy](https://github.com/sindresorhus/LaunchAtLogin-Legacy), which says: > If your app targets macOS 13 or later, check out [this modern version](https://github.com/sindresorhus/LaunchAtLogin-Modern) instead. A migration guide can be found [here](https://github.com/sindresorhus/LaunchAtLogin-Legacy/blob/main/before-after.md). See [sindresorhus/LaunchAtLogin-Modern](https://github.com/sindresorhus/LaunchAtLogin-Modern) for more info.
