+   :name: HTTP OTA Firmware Update on SiWx917
+   :relevant-api: wifi
+
+   Demonstrates HTTP/HTTPS OTA firmware update using SiWx917 on Zephyr.
+
+Overview
+********
+
+Application demonstrates how to perform HTTP/HTTPS OTA firmware updates on the
+SiWx917 platform using Zephyr RTOS. It connects to a Wi-Fi network, establishes
+an HTTPS connection, and downloads firmware
+updates from a remote server. The application showcases secure connectivity and
+OTA update mechanisms for IoT devices.
+
+Requirements
+************
+
+* SiWx917 development board with Wi-Fi support
+* HTTP server
+
+Configurations
+**************
+
+The following configurations can be modified in ``prj.conf``:
+
+* Wi-Fi Settings
+  * ``CONFIG_OTA_WIFI_SSID`` - Network name
+  * ``CONFIG_OTA_WIFI_PSK`` - Network password
+  * ``CONFIG_OTA_UPDATE_URL`` - OTA update URL
+
+Building and Running
+********************
+
+1. Configure required settings
+2. Build and Flash
+
+   .. zephyr-app-commands::
+      :app: siwx917_ota
+      :board: siwx917_rb4338a
+      :goals: build flash
+
+3. Run HTTP/HTTPS server
+
+Test the Application
+********************
+
+1. After flashing the SiWx91x, the device will scan for the specified AP and
+   attempt to connect if found.
+2. Once connected, the SiWx91x will initiate an HTTP/S connection to the specified
+   server and download the firmware binary.
+3. The OTA update process will be logged to the serial console.
+
+Note
+****
+
+This application is not for production.
