+# Bevy Engine
+Bevy is a modern, open-source game engine built in **Rust**. It emphasizes simplicity, modularity, and performance, making it an attractive choice for game developers looking for a data-driven, Entity-Component-System (ECS) architecture combined with modern rendering capabilities.
+
+## Entity Component System (ECS)
+
+* **Entity:** Unique identifier representing a game object.
+* **Component:** Plain data attached to entities.
+* **System:** Logic operating on entities with matching components, executed in parallel where possible.
+
+This design promotes separation of data and logic, enabling highly efficient, cache-friendly processing.
+
+## Basic Example
+
+A simple example creating a window and spawning a 2D sprite:
+
+```rust
+use bevy::prelude::*;
+
+fn main() {
+    App::new()
+        .add_plugins(DefaultPlugins)
+        .add_startup_system(setup)
+        .run();
+}
+
+fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
+    // Camera
+    commands.spawn(Camera2dBundle::default());
+
+    // Sprite
+    commands.spawn(SpriteBundle {
+        texture: asset_server.load("branding/icon.png"),
+        ..Default::default()
+    });
+}
+```
