+### Enabling HTTP/2

 Some features in Fiber, such as SendEarlyHints, require HTTP/2 or newer. If your app is served directly over HTTP/1.1, certain features may be ignored or not function as expected.
 
 To enable HTTP/2 in production, run Fiber behind a reverse proxy that upgrades connections. Popular choices include Nginx and Traefik.

-</details>\n\n### Configuring Fiber\n\nWhen your application is behind a proxy, you must configure Fiber to trust the proxy headers so that information like the client's IP address and protocol are correctly parsed. You can do this via the `ProxyHeader` configuration.\n\n```go\napp := fiber.New(fiber.Config{\n  // For Nginx, you might use X-Real-IP or X-Forwarded-For\n  ProxyHeader: fiber.HeaderXForwardedFor,\n})\n```\n\nFor more details, see the [configuration documentation on `ProxyHeader`](../api/fiber.md#proxyheader).
