+    **Quickstart: Importing and using the MAX31856**
+
+        Here is an example of using the :class:`MAX31856` class.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import board
+            from digitalio import DigitalInOut, Direction
+            import adafruit_max31856
+
+        Once this is done you can define your `board.SPI` object and define your sensor object
+
+        .. code-block:: python
+
+            spi = board.SPI()
+            cs = digitalio.DigitalInOut(board.D5)  # Chip select of the MAX31856 board.
+            sensor = adafruit_max31856.MAX31856(spi, cs)
+
+
+        Now you have access to the :attr:`temperature` attribute
+
+        .. code-block:: python
+
+            temperature = sensor.temperature
