 ### System Requirements
 
-- macOS 10.15 and Xcode 11.4 or later.
-- [Swift 5.2 or later](https://swift.org/download/) and Ubuntu 18.04 for Linux users.
+- [Swift 5.9.2 or later](https://swift.org/download/)
 
 ### Installation
 
-On macOS `carton` can be installed with [Homebrew](https://brew.sh/). Make sure you have Homebrew
-installed and then run:
+1. Create a directory for your project and make it current:
 
-```sh
-brew install swiftwasm/tap/carton
 ```
-
-You'll have to build `carton` from sources on Linux. Clone the repository and run
-`swift build -c release`, the `carton` binary will be located in the `.build/release`
-directory after that.
-Assuming you already have Homebrew installed, you can create a new Tokamak
-app by following these steps:
-
-1. Install `carton`:
-
-```
-brew install swiftwasm/tap/carton
+mkdir MyApp && cd MyApp
 ```
 
-If you had `carton` installed before this, make sure you have version 0.6.1 or greater:
+2. Initialize the project:
 
 ```
-carton --version
+swift package init --type executable
 ```
 
-2. Create a directory for your project and make it current:
-
-```
-mkdir TokamakApp && cd TokamakApp
+3. Add Tokamak and carton as dependencies to your `Package.swift`:
+
+```swift
+// swift-tools-version:5.8
+import PackageDescription
+let package = Package(
+    name: "MyApp",
+    platforms: [.macOS(.v11), .iOS(.v13)],
+    dependencies: [
+        .package(url: "https://github.com/TokamakUI/Tokamak", from: "0.11.0"),
+        .package(url: "https://github.com/swiftwasm/carton", from: "1.0.0"),
+    ],
+    targets: [
+        .executableTarget(
+            name: "MyApp",
+            dependencies: [
+                .product(name: "TokamakShim", package: "Tokamak")
+            ]),
+    ]
+)
 ```
 
-3. Initialize the project from a template with `carton`:
-
-```
-carton init --template tokamak
+4. Add your first view to `Sources/main.swift`:
+
+```swift
+import TokamakDOM
+
+@main
+struct TokamakApp: App {
+    var body: some Scene {
+        WindowGroup("Tokamak App") {
+            ContentView()
+        }
+    }
+}
+
+struct ContentView: View {
+    var body: some View {
+        Text("Hello, world!")
+    }
+}
 ```

+6. Open [http://127.0.0.1:8080/](http://127.0.0.1:8080/) in your browser to see the app
    running. You can edit the app source code in your favorite editor and save it, `carton`
    will immediately rebuild the app and reload all browser tabs that have the app open.

 ## Building and running the test suite with `carton`
 
 If you use [`carton`](https://carton.dev) to develop and build your app, as described in [our guide
-for browser apps](./browser-app.md), just run `carton test` in the
+for browser apps](./browser-app.md), just run `swift run carton test` in the
 root directory of your package. This will automatically build the test suite and run it with a WASI runtime for you.
