+## Socket Option Utility
+
+`set_socket_opt` is a convenience wrapper around `setsockopt` for setting integer socket options:
+
+```cpp
+auto sock = svr.socket();
+httplib::set_socket_opt(sock, IPPROTO_TCP, TCP_NODELAY, 1);
+```
+
+For time-based options, use `set_socket_opt_time` from the `detail` namespace:
+
+```cpp
+httplib::detail::set_socket_opt_time(sock, SOL_SOCKET, SO_RCVTIMEO, 5, 0); // 5 seconds
+```
+
+> [!TIP]
+> For most use cases, prefer `set_tcp_nodelay(true)` or `set_socket_options(callback)` on the Server/Client instead of calling `set_socket_opt` directly.
