+[file a new issue]: https://github.com/samsonjs/NotificationTask/issues/new
+
+### Supported Platforms
+
+This package is supported on iOS 16.0+ and macOS 12.0+.
+
+### Xcode
+
+When you're integrating this into an app with Xcode then go to your project's Package Dependencies and enter the URL `https://github.com/samsonjs/NotificationTask` and then go through the usual flow for adding packages.
+
+### Swift Package Manager (SPM)
+
+When you're integrating this using SPM on its own then add this to the list of dependencies your Package.swift file:
+
+```swift
+.package(url: "https://github.com/samsonjs/NotificationTask.git", .upToNextMajor(from: "0.1.0"))
+```
+
+and then add `"NotificationTask"` to the list of dependencies in your target as well.
+
+## Usage
+
+The simplest example uses a closure that receives the notification:
+
+```swift
+import NotificationTask
+
+@MainActor class SimplestVersion {
+    let task = NotificationTask(name: .NSCalendarDayChanged) { _ in
+        print("The date is now \(Date.now)")
+    }
+}
+```
+
+Example using context to avoid reference cycles with `self`:
+
+```swift
+import NotificationTask
+
+@MainActor class WithContext {
+    var notificationTask: NotificationTask?
+
+    init() {
+        notificationTask = NotificationTask(name: .NSCalendarDayChanged, context: self) { _self, _ in
+            _self.dayChanged()
+        }
+    }
+
+    func dayChanged() {
+        print("The date is now \(Date.now)")
+    }
+}
+```
+
+The closure is async so you can await in there if you need to.
