+To run Flame you need use the `GameWidget`, which is just another widget that can live anywhere in
+your widget tree. You can use it as the root widget of your app, or as a child of another widget.
+
+Here is a simple example of how to use the `GameWidget`:
+
+```dart
+import 'package:flame/game.dart';
+import 'package:flutter/material.dart';
+
+void main() {
+  runApp(
+    GameWidget(
+      game: FlameGame(),
+    ),
+  );
+}
+```
+
+In Flame we provide a concept called the Flame Component System (FCS), which is a way to organize
+your game objects in a way that makes it easy to manage them. You can read more about it in the
+[Components](flame/components.md) section.
+
+When you want to start a new game you either have to extend the `FlameGame` class or the `World`
+class. The `FlameGame` is the root of your game and is responsible for managing the game loop and
+the components. The `World` class is a component that can be used to create a world in your game.
+
+So to create a simple game you can do something like this:
+
+```dart
+import 'package:flame/game.dart';
+import 'package:flame/components.dart';
+import 'package:flutter/widgets.dart';
+
+void main() {
+  runApp(
+    GameWidget(
+      game: FlameGame(world: MyWorld()),
+    ),
+  );
+}
+
+class MyWorld extends World {
+  @override
+  Future<void> onLoad() async {
+    add(Player(position: Vector2(0, 0)));
+  }
+}
+```
+
+As you can see, we have created a `MyWorld` class that extends the `World` class. We have overridden
+the `onLoad` method to add a `Player` component (which doesn't exist yet) to the world. In the
+`FlameGame` class we by default have a `camera` that is watching the world, and by default it is
+looking at the (0, 0) position of the world in the center of the screen, to learn more about the
+camera and the world you can read the [Camera Component](flame/camera.md) section.
+
+The `Player` component can be whatever type of component that you want, to get started we recommend
+to use the `SpriteComponent` class, which is a component that can render a sprite (image) on the
+screen.
+
+For example something like this:
+
+```dart
+import 'package:flame/components.dart';
+import 'package:flame/geometry.dart';
+import 'package:flame/extensions.dart';
+
+class Player extends SpriteComponent {
+  Player({super.position}) :
+    super(size: Vector2.all(200), anchor: Anchor.center);
+
+  @override
+  Future<void> onLoad() async {
+    sprite = await Sprite.load('player.png');
+  }
+}
+```
+
+In this example, we have created a `Player` class that extends the `SpriteComponent` class. We have
+overridden the `onLoad` method to set the sprite of the component to a sprite that we load from an
+image file called `player.png`. The image has to be in the `assets/images` directory in your project
+(see the [Assets Directory Structure](flame/structure.md)) and you have to add it to the
+[assets section](https://docs.flutter.dev/ui/assets/assets-and-images) of your `pubspec.yaml` file.
+In this class we also set the size of the component to 200x200 and the [anchor](flame/components.md#anchor)
+to the center of the component by sending them to the `super` constructor. We also let the user of
+the `Player` class set the position of the component when creating it
+(`Player(position: Vector2(0, 0))`).
+
+To handle input on a component you can add any of our [input mixins](flame/inputs/inputs.md) to the
+component. For example, if you want to handle tap input you can add the `TapCallbacks` mixin to the
+player component, and receive tap events within the bounds of the player component. Or if you want
+to handle tap input on the whole world you can add the `TapCallbacks` mixin to the extended `World`
+class.
+
+The following example handles taps on the player component, and when the player component is
+tapped the size of the player will increase by 50 pixels in both width and height.
+
+```dart
+import 'package:flame/components.dart';
+import 'package:flame/geometry.dart';
+import 'package:flame/extensions.dart';
+
+class Player extends SpriteComponent with TapCallbacks {
+  Player({super.position}) :
+    super(size: Vector2.all(200), anchor: Anchor.center);
+
+  @override
+  Future<void> onLoad() async {
+    sprite = await Sprite.load('player.png');
+  }
+  
+  @override
+  void onTapUp(TapUpInfo info) {
+    size += Vector2.all(50);
+  }
+}
+```
+
+This is just a simple example of how to get started with Flame, there are many more features that you
+can use (and probably need) to create your game, but this should give you a good starting point.
+
+You can also check out the [awesome flame repository](https://github.com/flame-engine/awesome-flame#user-content-articles--tutorials),
+it contains quite a lot of good tutorials and articles written by the community to get you started
+with Flame.
