+Unity2LibPdScene Notes
+----------------------
+This scene demonstrates how to communicate from libpd to Unity.
+
+In our PD patch this is relatively simple: we just create a send object to send
+data to Unity.
+
+
+On the Unity end, however, things are a bit more complicated. The required steps
+are:
+
+1.) Bind() to the desired send object. libpd will not make send signals
+    available to Unity by default. We need to tell it we are interested in
+	specific signals. We do this using the Bind() function in LibPdInstance,
+	e.g. pdPatch.Bind("BangTest"); (if BangTest is the name of our send object).
+
+2.) Write a function that will be called whenever that send object sends a
+    signal to us. The signature of that function will have to match the
+	signature LibPdInstance is expecting. For instance, a function that reacts
+	to bang signals would look like this:
+
+	public void BangReceive(string name)
+
+	And a function that reacts to float (or number) signals would look like
+	this:
+
+	public void FloatReceive(string name, float value)
+
+	Where name is the name of the send object, and value is the float value that
+	was sent from your PD patch.
+
+	You can see a full list of function signatures on the wiki:
+	https://github.com/LibPdIntegration/LibPdIntegration/wiki/libpd2unity#unityevents
+
+3.) Connect your LibPdInstance Component to the above function. LibPdInstance
+	uses Unity events for this. If you expand the Pure Data Events header you
+	will see a list of 5 UnityEvent widgets, one for each of the signal types
+	which can be sent from your PD patch.
+
+	To connect to your function, you need to click the + button for your
+	desired signal type, then drag the GameObject containing your receive
+	script into the 'None (object)' box.
+
+	Then, if you click the drop-down that says 'No Function', you will get a
+	list of possible destinations. Select your receiving script/Component, and
+	then, under the Dynamic header, select the receive function you created in
+	the previous step.
+
+	Note: You will see 2 copies of your function in that final menu: one under
+	'Dynamic', one under 'Static'. It is important that you select the entry
+	under 'Dynamic'; the one under 'Static' will not work for our purposes.
