 Getting the temperature in Celsius is easy! First, import all of the pins from

+    **Quickstart: Importing and using the MCP9808**
+
+        Here is an example of using the :class:`MCP9808` class.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import board
+            import adafruit_mcp9808
+
+        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
+            mcp = adafruit_mcp9808.MCP9808(i2c_bus)
+
+        Now you have access to the change in temperature using the
+        :attr:`temperature` attribute. This temperature is in Celsius.
+
+        .. code-block:: python
+
+            temperature = mcp.temperature
