+# System Temperature Desklet
+
+This desklet displays the temperature of a specific thermal zone on your system. To configure it correctly, you need to specify the path to the thermal zone's temperature file in the desklet settings.
+
+## Finding the Correct Temperature File
+
+1. **Locate Thermal Zones:**
+
+   Thermal zone files are usually located under `/sys/class/thermal/`. You can list them with the command:
+
+   ```bash
+   ls /sys/class/thermal/
+   ```
+
+2. **Identify the Relevant Thermal Zone:**
+
+   Each thermal_zoneX directory represents a thermal zone. Inside, you'll find a file that contains the temperature data (in millidegrees Celsius).
+
+3. **Set the Path in Desklet Settings:**
+
+   In the desklet settings, specify the full path to the temperature file you want to monitor, such as:
+
+   `/sys/class/thermal/thermal_zone2/temp`
