 # starship
+
+Here's a basic "Hello, world!" example:
+
+```ts
+import {
+  StarshipConfig,
+  StarshipInit,
+  StarshipDestroy,
+  StarshipUpdate,
+  run,
+  drawText,
+  FONT_8x8,
+  isButtonDown,
+  Button,
+} from '@vsmode/starship'
+
+// The game state
+interface GameState {
+  x: 0
+  y: 0
+}
+
+// Set game configuration options
+const config: StarshipConfig = {
+  title: 'My Game',
+  canvas: { x: 256, y: 144 },
+  fps: 60,
+}
+
+// Creates the initial game state
+const init: StarshipInit<GameState> = () => {
+  return {
+    x: 0,
+    y: 0,
+  }
+}
+
+// Do any clean up here before the game ends
+const destroy: StarshipDestroy<GameState> = _ => {
+  // ...
+}
+
+// This runs every frame
+const update: StarshipUpdate<GameState> = (state, _) => {
+  clear()
+  drawText(FONT_8x8, 'Hello, World!', state)
+  if (isButtonDown(Button.Up)) {
+    state.y--
+  }
+  if (isButtonDown(Button.Down)) {
+    state.y++
+  }
+  if (isButtonDown(Button.Left)) {
+    state.x--
+  }
+  if (isButtonDown(Button.Right)) {
+    state.x++
+  }
+}
+
+// Start the game! :)
+run(config, init, destroy, update)
+
+```
