 # gdpd
 
-Godot add-on for loading and processing Pure Data patches 
+gdpd is a Godot add-on for loading and processing Pure Data patches.
+
+# Using
+
+In a script, 
+
+1. Initalize gdpd
+
+```python
+onready var gdpd = load("res://addons/gdpd/bin/gdpd.gdns").new()
+```
+
+2. Initialize the audio inputs and outputs
+
+```python
+#retrieve the list of available input and outputs
+var inps = _gdpd.get_available_input_devices()
+var outs = _gdpd.get_available_output_devices()
+	
+#initialise the first ones
+_gdpd.init_devices(inps[0], outs[0])
+```
+
+4. Load a patch
+
+```python
+var patch = ProjectSettings.globalize_path("res://patch.pd")
+
+var patch_name = patch.split("/")[-1]
+var patch_dir = patch.trim_suffix(patch_name)
+
+gdpd.openfile(patch_name, patch_dir)
+```
+
+5. Send a message to the patch
+
+```python
+#send message to [receive from_godot] with one symbol
+_gdpd.start_message(1)
+_gdpd.add_symbol("hello")
+_gdpd.finish_list("from_godot")
+```
+
+6. Subscribe and receive messages from the patch
+
+```python
+func _ready :
+	#listen to messages sent with [send to_godot]
+	_gdpd.subscribe("to_godot")
+
+
+func _process :
+	while _gdpd.has_message() :
+		#msg is an array with the list of symbols/floats sent to to_godot
+		var msg = _gdpd.get_next()
+		print("got message from pd ", msg)
+```
+
+
+For a full working example, open the Godot project in the demo folder.
