 ## Installation
 
+### Swift Package Manager
+
+The [Swift Package Manager](https://swift.org/package-manager/) is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.
+
+#### Manifest File
+
+Add Mocker as a package to your `Package.swift` file and then specify it as a dependency of the Target in which you wish to use it.
+
+```swift
+import PackageDescription
+
+let package = Package(
+    name: "MyProject",
+    platforms: [
+       .macOS(.v10_15)
+    ],
+    dependencies: [
+        .package(url: "https://github.com/WeTransfer/UINotifications.git", .upToNextMajor(from: "1.3.0"))
+    ],
+    targets: [
+        .target(
+            name: "MyProject",
+            dependencies: ["UINotifications"]),
+        .testTarget(
+            name: "MyProjectTests",
+            dependencies: ["MyProject"]),
+    ]
+)
+```
+
