+# Three.js
+
+> Three.js is a cross-browser JavaScript library for creating 3D graphics using WebGL and WebGPU.
+
+## Instructions for Large Language Models
+
+When generating Three.js code, follow these guidelines:
+
+### 1. Use Import Maps (Not Old CDN Patterns)
+
+WRONG - outdated pattern:
+```html
+<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js"></script>
+```
+
+CORRECT - modern pattern (always use latest version):
+```html
+<script type="importmap">
+{
+  "imports": {
+    "three": "https://cdn.jsdelivr.net/npm/three@0.182.0/build/three.module.js",
+    "three/addons/": "https://cdn.jsdelivr.net/npm/three@0.182.0/examples/jsm/"
+  }
+}
+</script>
+<script type="module">
+import * as THREE from 'three';
+import { OrbitControls } from 'three/addons/controls/OrbitControls.js';
+</script>
+```
+
+### 2. Choosing Between WebGLRenderer and WebGPURenderer
+
+Three.js maintains both renderers:
+
+**Use WebGLRenderer** (default, mature):
+- Maximum browser compatibility
+- Well-established, many years of development
+- Most examples and tutorials use this
+
+```js
+import * as THREE from 'three';
+const renderer = new THREE.WebGLRenderer();
+```
+
+**Use WebGPURenderer** when you need:
+- Custom shaders/materials using TSL (Three.js Shading Language)
+- Compute shaders
+- Advanced node-based materials
+
+```js
+import * as THREE from 'three/webgpu';
+const renderer = new THREE.WebGPURenderer();
+await renderer.init();
+```
+
+### 3. TSL (Three.js Shading Language)
+
+When using WebGPURenderer, use TSL instead of raw GLSL for custom materials:
+
+```js
+import { texture, uv, color } from 'three/tsl';
+
+const material = new THREE.MeshStandardNodeMaterial();
+material.colorNode = texture( myTexture ).mul( color( 0xff0000 ) );
+```
+
+TSL benefits:
+- Works with both WebGL and WebGPU backends
+- No string manipulation or onBeforeCompile hacks
+- Type-safe, composable shader nodes
+- Automatic optimization
+
+### 4. NodeMaterial Classes (for WebGPU/TSL)
+
+When using TSL, use node-based materials:
+- MeshBasicNodeMaterial
+- MeshStandardNodeMaterial
+- MeshPhysicalNodeMaterial
+- LineBasicNodeMaterial
+- SpriteNodeMaterial
