+
+Overview
+********
+
+A sample application that demonstrates the DNS client and ICMP functionality.
+This program will get the IP address of the given hostname and the ICMP will
+initiate a PING request to the address obtained from the DNS client.
+
+Requirements
+************
+
+* Windows PC (Remote PC).
+* SiWx91x Wi-Fi Evaluation Kit(SoC).
+
+Configuration Parameters
+************************
+The below confgurations are available in app_config.h file
+
+#define SSID 				"SiWx91x_AP"		                  // Wi-Fi Network Name
+#define PSK	 				"12345678"		                  // Wi-Fi Password
+#define SECURITY_TYPE	WIFI_SECURITY_TYPE_PSK			   // Wi-Fi Security Type: WIFI_SECURITY_TYPE_NONE/WIFI_SECURITY_TYPE_WPA_PSK/WIFI_SECURITY_TYPE_PSK
+#define CHANNEL_NO		WIFI_CHANNEL_ANY				      // Wi-Fi channel
+#define HOSTNAME			"www.zephyrproject.org"          //Hostname to ping
+
+Building and Running
+********************
+
+* This sample can be found under :zephyr_file:`zephyr/samples/boards/siwx91x/siwx91x_sample_app` in the Zephyr tree.
+
+* Build:- west build -b siwx917_rb4338a samples/boards/siwx91x/siwx91x_sample_app/ -p
+
+* Flash:- west flash
+
+Test the Application
+********************
+* Open any serial console to view logs.
+* After program gets executed, SiWx91x EVK will be connected to an Access Point with configured **SSID** and **PSK**
+* The device will start sending ping requests to the given hostname and the response can be seen in network_event_handler().
