 Of course, you must import the library to use it:

-    import busio

     import adafruit_ds1307
     import time
 
 All the Adafruit RTC libraries take an instantiated and active I2C object
-(from the ``busio`` library) as an argument to their constructor. The way to
+(from the ``board`` library) as an argument to their constructor. The way to
 create an I2C object depends on the board you are using. For boards with labeled
 SCL and SDA pins, you can:
 
 .. code:: python
 
-    from board import *
-
-You can also use pins defined by the onboard ``microcontroller`` through the
-``microcontroller.pin`` module.
+    import board
 
 Now, to initialize the I2C bus:
 
 .. code:: python
 
-    myI2C = busio.I2C(SCL, SDA)
+    i2c = board.I2C()
 
 Once you have created the I2C interface object, you can use it to instantiate
 the RTC object:
 
 .. code:: python
 
-    rtc = adafruit_ds1307.DS1307(myI2C)
+    rtc = adafruit_ds1307.DS1307(i2c)
 
 To set the time, you need to set ``datetime`` to a `time.struct_time` object:

+    **Quickstart: Importing and using the device**
+
+        Here is an example of using the :class:`DS1307` class.
+        First you will need to import the libraries to use the sensor
+
+        .. code-block:: python
+
+            import time
+            import board
+            import adafruit_ds1307
+
+        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
+            rtc = adafruit_ds1307.DS1307(i2c)
+
+        Now you can give the current time to the device.
+
+        .. code-block:: python
+
+            t = time.struct_time((2017, 10, 29, 15, 14, 15, 0, -1, -1))
+            rtc.datetime = t
+
+        You can access the current time accessing the :attr:`datetime` attribute.
+
+        .. code-block:: python
+
+            current_time = rtc.datetime
