+Class example template
+--------------------------------------------------------------------------------
+When documenting classes, you could use the following template to illustrate the basic class functioning.
+it is closely related with the simpletest, however this will display the information in the readthedocs
+documentation.
+The advantage of using this, is users will be familiar with this as it is used across libraries
+
+This is an example for a AHT20 temperature sensor. You could locate this after the class parameter
+definitions.
+
+
+.. code-block:: python
+
+    """
+
+    **Quickstart: Importing and using the AHT10/AHT20 temperature sensor**
+
+        Here is an example of using the :class:`AHTx0` class.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import board
+            import adafruit_ahtx0
+
+        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
+            aht = adafruit_ahtx0.AHTx0(i2c)
+
+        Now you have access to the temperature and humidity using
+        the :attr:`temperature` and :attr:`relative_humidity` attributes
+
+        .. code-block:: python
+
+            temperature = aht.temperature
+            relative_humidity = aht.relative_humidity
