+
+    **Quickstart: Importing and using the SGP40 temperature sensor**
+
+        Here is one way of importing the `SGP40` class so you can use it with the name ``sgp``.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import busio
+            import board
+            import adafruit_sgp40
+
+        Once this is done you can define your `busio.I2C` object and define your sensor object
+
+        .. code-block:: python
+
+            i2c = busio.I2C(board.SCL, board.SDA)
+            sgp = adafruit_sgp40.SGP40(i2c)
+
+        Now you have access to the raw gas value using the :attr:`raw` attribute
+
+        .. code-block:: python
+
+            raw_gas_value = sgp.raw
+
