+<h4>Creating an HDP Application</h4>
+
+<p>Here are the basic steps involved in creating an Android HDP application:</p>
+<ol>
+
+  <li>Get a reference to the {@link android.bluetooth.BluetoothHealth} proxy
+object. <p>Similar to regular headset and A2DP profile devices, you must call
+{@link android.bluetooth.BluetoothAdapter#getProfileProxy getProfileProxy()}
+with a {@link android.bluetooth.BluetoothProfile.ServiceListener} and the {@link
+android.bluetooth.BluetoothProfile.ServiceListener#HEALTH} profile type to
+establish a connection with the profile proxy object.</p> </li>
+
+  <li>Create a {@link android.bluetooth.BluetoothHealthCallback} and register an
+application configuration 
+({@link android.bluetooth.BluetoothHealthAppConfiguration})
+that acts as a health
+sink.</li>
+
+  <li>Establish a connection to a health device.  Some devices will initiate the
+connection.  It is unnecessary to carry out this step for those devices.</li>
+
+  <li>When connected successfully to a health device, read/write to the health
+device using the file descriptor. <p>The received data needs to be interpreted
+using a health manager which implements the IEEE 11073-xxxxx
+specifications.</p></li>
+
+  <li>When done, close the health channel and unregister the application.  The
+channel also closes when there is extended inactivity.</li>
+</ol>
