+# Asio UDP echo server example
+
+Simple Asio UDP echo server using WiFi STA or Ethernet.
+
+## Example workflow
+
+- Wi-Fi or Ethernet connection is established, and IP address is obtained.
+- Asio UDP server is started on port number defined through the project configuration
+- Server receives and echoes back messages transmitted from client
+
+## Running the example
+
+- Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
+- Set server port number in menuconfig, "Example configuration".
+- Run `idf.py -p PORT flash monitor` to build and upload the example to your board and connect to it's serial terminal.
+- Wait for the board to connect to WiFi or Ethernet (note the IP address).
+- You can now send a UDP message and check it is repeated, for example using netcat `nc -u IP PORT`.
+
+See the README.md file in the upper level 'examples' directory for more information about examples.
