+# Firmware Node Application
+
+This Zephyr application provides firmware management capabilities for the irrigation system.
+
+**Tested on Zephyr 4.1.99**
+
+## Features
+
+### Step 1: Shell with Reset Command
+- Shell interface with custom "reset" command
+- Warm reboot functionality
+
+### Planned Features
+- MCUboot support with partition manager
+- Firmware version display
+- MCUmgr support for OTA updates
+
+## Building
+
+```bash
+west build -p auto -b weact_stm32g431_core apps/firmware_node -- -DBOARD_FLASH_RUNNER=blackmagicprobe
+```
+
+## Flashing
+
+```bash
+west flash
+```
+
+## Usage
+
+Connect to the device via serial console and use the shell:
+- `reset` - Reboot the system
+- `help` - Show available commands
