+    **Quickstart: Importing and using the device**
+
+        Here is an example of using the :class:`TSL2591` class.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import board
+            import adafruit_tsl2591
+
+        Once this is done you can define your `board.I2C` object and define your sensor object
+
+        .. code-block:: python
+
+            i2c = board.I2C()  # uses board.SCL and board.SDA
+            sensor = adafruit_tsl2591.TSL2591(i2c)
+
+        Now you have access to the :attr:`lux`, :attr:`infrared`
+        :attr:`visible` and :attr:`full_spectrum` attributes
+
+        .. code-block:: python
+
+            lux = sensor.lux
+            infrared = sensor.infrared
+            visible = sensor.visible
+            full_spectrum = sensor.full_spectrum
