+### Usage
+
+</div>
+
+##### To use zlib in swift, add zlib as a package dependency in your project's Package.swift file.
+```swift
+dependencies: [
+  .package(url: "https://github.com/wabiverse/icu.git", from: "76.1.0"),
+]
+```
+
+
+##### Then, for any target you'd like, add the zlib product as a target dependency, a complete example.
+```swift
+// swift-tools-version: 5.10
+import PackageDescription
+
+let package = Package(
+  name: "MyPackage",
+  products: [
+    .library(
+      name: "MyLibrary",
+      targets: ["MyLibrary"]
+    ),
+  ],
+  dependencies: [
+    .package(url: "https://github.com/wabiverse/icu.git", from: "76.1.0")
+  ],
+  targets: [
+    .target(
+      name: "MyLibrary",
+      dependencies: [
+        /* add the icu product as a library dependency. */
+        .product(name: "icuin", package: "icu"),
+      ]
+    ),
+  ]
