+
+    **Quickstart: Importing and using the PMSA003I Air quality sensor**
+
+        Here is one way of importing the `PM25_I2C` class so you can use it with the name ``pm25``.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import board
+            import busio
+            from adafruit_pm25.i2c import PM25_I2C
+
+        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, frequency=100000)

+            pm25 = PM25_I2C(i2c, reset_pin)
+
+
+        Now you have access to the air quality data using the class function
