This is usually solved by making it a preference that is disabled by default. Many apps also let the user activate it in a welcome screen.*
+This package comes with a `LaunchAtLogin.Toggle` view which is like the built-in `Toggle` but with a predefined binding and label. Clicking the view toggles “launch at login” for your app.
+
+```swift
+struct ContentView: View {
+	var body: some View {
+		LaunchAtLogin.Toggle()
+	}
+}
+```
+
+The default label is `"Launch at login"`, but it can be overridden for localization and other needs:
+
+```swift
+struct ContentView: View {
+	var body: some View {
+		LaunchAtLogin.Toggle {
+			Text("Launch at login")
+		}
+	}
+}
+```
+
+Alternatively, you can use `LaunchAtLogin.observable` as a binding with `@ObservedObject`:
+
+```swift
+import SwiftUI
+import LaunchAtLogin
+
+struct ContentView: View {
+	@ObservedObject private var launchAtLogin = LaunchAtLogin.observable
+
+	var body: some View {
+		Toggle("Launch at login", isOn: $launchAtLogin.isEnabled)
+	}
+}
+```
+
+#### Combine
+
+Just subscribe to `LaunchAtLogin.publisher`:
+
+```swift
+import Combine
+import LaunchAtLogin
+
+final class ViewModel {
+	private var isLaunchAtLoginEnabled = LaunchAtLogin.isEnabled
+	private var cancellables = Set<AnyCancellable>()
+
+	func bind() {
+		LaunchAtLogin
+			.publisher
+			.assign(to: \.isLaunchAtLoginEnabled, on: self)
+			.store(in: &cancellables)
+	}
+}
+```
+
+#### Storyboards
+
+Bind the control to the `LaunchAtLogin.kvo` exposed property:
+
+```swift
+import Cocoa
+import LaunchAtLogin
+
+final class ViewController: NSViewController {
+	@objc dynamic var launchAtLogin = LaunchAtLogin.kvo
+}
+```

 ## How does it work?

 ## FAQ
 
-#### The size of my app increased after adding `LaunchAtLogin`
+#### I'm getting a “No such file or directory” error when archiving my app
+
+Please ensure that the LaunchAtLogin run script phase is still below the “Embed Frameworks” phase. The order could have been accidentally changed.
+
+The build error usually presents itself as:
+
+```
+cp: […]/Resources/LaunchAtLoginHelper.app: No such file or directory
+rm: […]/Resources/copy-helper.sh: No such file or directory
+Command PhaseScriptExecution failed with a nonzero exit code
+```
+
+#### The size of my app increased after adding `LaunchAtLogin` when using Carthage
 
 The bundled launcher app is written in Swift and hence needs to embed the Swift runtime libraries. If your project targets macOS 10.14.4 or later, you can avoid embedding the Swift runtime libraries. First, open `./Carthage/Checkouts/LaunchAtLogin/LaunchAtLogin.xcodeproj` and set the deployment target to the same as your app, and then run `$ carthage build`. You'll have to do this each time you update `LaunchAtLogin`.
 
+This is not a problem when using Swift Package Manager.

 #### My app doesn't show up in “System Preferences › Users & Groups › Login Items”

 #### Can you support CocoaPods?

 #### I'm getting a `'SMCopyAllJobDictionaries' was deprecated in OS X 10.10` warning
 
 Apple deprecated that API without providing an alternative. Apple engineers have [stated that it's still the preferred API to use](https://github.com/alexzielenski/StartAtLoginController/issues/12#issuecomment-307525807). I plan to use it as long as it's available. There are workarounds I can implement if Apple ever removes the API, so rest assured, this module will be made to work even then. If you want to see this resolved, submit a [Feedback Assistant](https://feedbackassistant.apple.com) report with [the following text](https://github.com/feedback-assistant/reports/issues/16). There's unfortunately still [no way to suppress warnings in Swift](https://stackoverflow.com/a/32861678/64949).
 
+#### I can't see the `LaunchAtLogin.bundle` in my debug build or I get a notarization error for developer ID distribution
+
+As discussed [here](https://github.com/sindresorhus/LaunchAtLogin/issues/50), this package tries to determine if you're making a release or debug build and clean up its install accordingly. If your debug build is missing the bundle or, conversely, your release build has the bundle and it causes a code signing error, that means this has failed.
+
+The script's determination is based on the “Build Active Architecture Only” flag in build settings. If this is set to `YES`, then the script will package LaunchAtLogin for a debug build. You must set this flag to `NO` if you plan on distributing the build with codesigning.
