+# Bun Frontend Template
 
-a simple bun frontend starting point i made and use
+A minimal, fast, and type-safe web server template built with [Bun](https://bun.sh) and TypeScript. Features file-system based routing, static file serving, WebSocket support, and structured logging.
+
+## Configuration
+
+### Environment Variables
+
+| Variable | Description | Default | Required |
+|----------|-------------|---------|----------|
+| `HOST` | Server host address | `0.0.0.0` | ✅ |
+| `PORT` | Server port | `8080` | ✅ |
+| `NODE_ENV` | Environment mode | `production` | ❌ |
+
+### Creating Routes
+
+Routes are automatically generated from files in `src/routes/`. Each route file exports:
+
+```typescript
+// src/routes/example.ts
+const routeDef: RouteDef = {
+  method: "GET",                    // HTTP method(s)
+  accepts: "application/json",      // Content-Type validation
+  returns: "application/json",      // Response Content-Type
+  needsBody?: "json" | "multipart"  // Optional body parsing, dont include if neither are required
+};
+
+async function handler(
+  request: ExtendedRequest,
+  requestBody: unknown,
+  server: BunServer
+): Promise<Response> {
+  return Response.json({ message: "Hello World" });
+}
+
+export { handler, routeDef };
+```
+
+### Route Features

+- **Content-Type Validation** - Request/response content type enforcement
+- **Body Parsing** - Automatic JSON/FormData parsing
