+Codesandbox provider for ComputeSDK - Execute code in Codesandbox development environments.
+
+## Installation & Setup
+
+```bash
+npm install computesdk
+
+# add to .env file
+COMPUTESDK_API_KEY=your_computesdk_api_key
+
+CSB_API_KEY=your_codesandbox_api_key
+```
+
+
+## Usage
+
+### With ComputeSDK
+
+```typescript
+import { compute } from 'computesdk';
+// auto-detects provider from environment variables
+
+// Create sandbox
+const sandbox = await compute.sandbox.create();
+
+// Execute code
+const result = await sandbox.runCode('print("Hello from Codesandbox!")');
+console.log(result.stdout); // "Hello from Codesandbox!"
+
+// Clean up
+await compute.sandbox.destroy(sandbox.sandboxId);
+```
+
+### Configuration Options
+
+```typescript
+interface CodesandboxConfig {
+  /** CodeSandbox API key - if not provided, will fallback to CSB_API_KEY environment variable */
+  apiKey?: string;
+  /** Template to use for new sandboxes */
+  templateId?: string;
+  /** Execution timeout in milliseconds */
+  timeout?: number;
+}
+```
+
+
+## Explicit Provider Configuration
+If you prefer to set the provider explicitly, you can do so as follows:
+```typescript
+import { compute } from 'computesdk';
+
+compute.setConfig({
+   computesdkApiKey: process.env.COMPUTESDK_API_KEY,
+   provider: 'codesandbox',
+   codesandbox: {
+     apiKey: process.env.CSB_API_KEY
+   }
+});
+
+const sandbox = await compute.sandbox.create();
+```
+
+## Runtime Detection
+
+The provider automatically detects the runtime based on code patterns:
+
+**Python indicators:**
+- `print` statements
+- `import` statements  
+- `def` function definitions
+- Python-specific syntax (`f"`, `__`, etc.)
+
+**Default:** Node.js for all other cases
