+### Websocket support in `http_server`
+
+Websocket echo server is build on top of the HTTP server component using [Websocket server](https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/protocols/esp_http_server.html#websocket-server) configuration.
+This feature is very limited, and a special care must be taken while implementing websocket URI handlers.
+
+#### Configure URI handler
+
+We register the URI handler with the standard API `httpd_register_uri_handler()` with `is_websocket` enabled and other optional parameters:
+
+```c
+static const httpd_uri_t ws_uri_handler_options = {
+        ... // httpd options
+        
+        .is_websocket = true,               // Mandatory: set to `true` to handler websocket protocol
+        .handle_ws_control_frames = false,  // Optional: set to `true` for the handler to receive control packets, too
+        .supported_subprotocol = "chat",    // Optional: set supported subprotocol for this handler
+};
+
+```
+
+#### Implement URI handler
+
+The URI handler is called on every URI request, but also before the websocket handshake, so it is very important to check the request type before reading websocket frame:
+
+```c
+    // beginning of the ws URI handler
+    if (req->method == HTTP_GET) {
+        // action before ws handshake
+        return ESP_OK;
+    }
+    // action after the handshake (read frames)
+```
+
+#### Handling incoming data
+
+To receive websocket frames, use `httpd_ws_recv_frame()` after the websocket handshake, with `httpd_ws_frame_t` parameters set accordingly:
+* `payload` to a valid buffer for the received data
+* `len` set to `0` for the first call of `httpd_ws_recv_frame()`. Note that this value is used to indicate the packet length has been read in the previous call if we use dynamic buffers.
 
 `httpd_ws_recv_frame` support two ways to get frame payload.
 * Static buffer -- Allocate maximum expected packet length (either statically or dynamically) and call `httpd_ws_recv_frame()` referencing this buffer and it's size. (Unnecessarily large buffers might cause memory waste)
