 Support Classes
 ---------------
 
+There are a few support classes in this module that make it simpler to build
+the most common BACnet devices.
+
 .. class:: CurrentDateProperty(Property)
 
-This is a long line of text.
+    This class is a specialized readonly property that always returns the
+    current date as provided by the operating system.
+
+    .. method:: ReadProperty(self, obj, arrayIndex=None)
+
+        Returns the current date as a 4-item tuple consistent with the
+        Python implementation of the :class:`Date` primitive value.
+
+    .. method:: WriteProperty(self, obj, value, arrayIndex=None, priority=None)
+
+        Object instances of this class are readonly, so this method raises
+        a `writeAccessDenied` error.
 
 .. class:: CurrentTimeProperty(Property)
 
-This is a long line of text.
+    This class is a specialized readonly property that always returns the
+    current local time as provided by the operating system.
+
+    .. method:: ReadProperty(self, obj, arrayIndex=None)
+
+        Returns the current date as a 4-item tuple consistent with the
+        Python implementation of the :class:`Time` primitive value.
+
+    .. method:: WriteProperty(self, obj, value, arrayIndex=None, priority=None)
+
+        Object instances of this class are readonly, so this method raises
+        a `writeAccessDenied` error.
 
 .. class:: LocalDeviceObject(DeviceObject)
 
-This is a long line of text.
+    The :class:`LocalDeviceObject` is an implementation of a
+    :class:`DeviceObject` that provides default implementations for common
+    properties and behaviors of a BACnet device.  It has default values for
+    communications properties, returning the local date and time, and
+    the `objectList` property for presenting a list of the objects in the
+    device.
