+=============================
+Sensirion SHTC3 Sensor Driver
+=============================
+
+This driver provides support for the Sensirion SHTC3 temperature and humidity sensor
+using the uORB sensor framework.
+
+It provides two uORB topics:
+- ``SENSOR_TYPE_AMBIENT_TEMPERATURE``
+- ``SENSOR_TYPE_RELATIVE_HUMIDITY``
+
+Configuration
+-------------
+
+To enable the driver, select ``CONFIG_SENSORS_SHTC3=y`` in your board configuration.
+You can configure the I2C frequency via ``CONFIG_SHTC3_I2C_FREQUENCY`` (default is 400kHz).
