+# Simplifying WebGPU with This Framework
+
+WebGPU’s native API is complex and verbose. This framework reduces that complexity by providing simple classes and methods to manage shaders, buffers, and execution. Instead of handling low-level GPU commands, you focus on your logic.
+
+## 1. Loading and Using a Shader
+
+**Without Framework:**
+
+```
+Manual setup of device, pipeline, bind groups, etc. Very verbose and error-prone
+const shaderModule = device.createShaderModule({ code: wgslSource });
+const pipeline = device.createComputePipeline({ ... });
+// Setup bind groups and command encoder manually
+```
+
+**With Framework:**
+
+```
+const shader = new Shader( "myComputeShader.wgsl" );
+
+await shader.compile();
+
+shader.setVariable( "someUniform", 42 );
+
+shader.execute( 64 ); // runs compute with 64 workgroups
+```
+
+The framework loads, compiles, sets uniforms, and dispatches the compute shader with simple method calls.
+
+## 2. Setting Buffers
+
+**Without Framework:**
+
+```
+Create GPU buffer, write data, create bind group manually
+```
+
+**With Framework:**
+
+```
+const dataBuffer = gpu.createBuffer( new Float32Array([1, 2, 3]) );
+
+shader.setBuffer( "inputBuffer", dataBuffer );
+```
+
+Buffers are bound by name with a simple call.
+
+## 3. Rendering to Canvas
+
+**Without Framework:**
+
+```
+Create render pipeline, set vertex buffers, encode commands manually
+```
+
+**With Framework:**
+
+```
+shader.setCanvas( canvasElement );
+
+shader.setAttributes( vertexData );
+
+shader.execute();
+```
+
+The framework handles pipeline creation, drawing commands, and presentation automatically.
+
+## 4. Camera and Matrix Utilities
+
+**Example:**
+
+```
+const camera = new Camera();
+
+camera.position.set( 0, 1, 5 );
+
+camera.updateViewMatrix();
+
+shader.setVariable( "viewMatrix", camera.viewMatrix );
+```
+
+The framework provides built-in classes for common math tasks.
+
+## 5. Event Handling
+
+**Example:**
+
+```
+const events = new EventManager( canvasElement );
+
+events.on( "mouseMove", (event) => {
+  camera.rotate( event.deltaX, event.deltaY );
+  shader.setVariable( "viewMatrix", camera.viewMatrix );
+  shader.execute();
+});
+```
+
+Separates input handling cleanly from GPU logic.
+
+## Summary Table
+
+| Task | WebGPU Native API | This Framework |
+| --- | --- | --- |
+| Load and compile shader | Many steps, manual setup | One line with `new Shader()` + `compile()` |
+| Set uniforms | Define bind groups and layouts | Simple `setVariable()` calls |
+| Bind buffers | Manual buffer creation and binding | `setBuffer()` by name |
+| Execute compute | Command encoder and dispatch calls | `execute(workgroupCount)` method |
+| Render to canvas | Complex pipeline and draw calls | `setCanvas()`, `setAttributes()`, `execute()` |
+| Handle math and camera | External libs or manual math | Built-in Matrix4, Camera classes |
+| Input handling | Manual event listeners | `EventManager` handles input cleanly |
+
+---
+
+This framework hides the low-level complexity behind a clean, simple API that accelerates WebGPU development and makes GPU programming accessible and maintainable.
