-### Setting up with Carthage
-
-[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.
-
-You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
-
-```bash
-$ brew update
-$ brew install carthage

+github "marmelroy/Zip" ~> 1.1
+```
+
+### Setting up with [Swift Package Manager](https://swift.org/package-manager)
+To use Zip with Swift Package Manager, add it to your package's dependencies:
+```swift
+.package(url: "https://github.com/marmelroy/Zip.git", .upToNextMinor(from: "1.1.0"))
