+Repo for MATLAB-Code used on a RedPitaya device
+-----
+
+Basic functionalities provided to access the RedPitaya via MQTT.  
 A oscilloscope and a signalgenerator are implemented via MQTT.
 
-Structure:
-1. lib folder
-The "cosaMqttClient.py" contains MQTT-functions to send messages understood by a python library.
-And "mqtt_py_matlab.m" contains MQTT-functions used in MATLAB.
+### Hardware requirements:
+
+RedPitaya Stemlab Board 125-14 (V1.1)  
+5 Volt RedPitaya PSU  
+Ethernet Cable / Wifi-Stick  
+
+### Software requirements:
+MATLAB installed  
+Python 3 installed (3.8 tested)  
+Mosquitto MQTT Client installed  
+MQTT Broker access  
+
+
+### Folder structure:
+
+#### 1. [lib](./lib):
+
+The "cosaMqttClient.py" contains MQTT-functions to send messages understood by a python library.  
+And "mqtt_py_matlab.m" contains MQTT-functions used in MATLAB.  
 
-    1. redpitaya folder:
 
-    Contains classes to store the structure of the oscilloscope signalgenerator.
-    The "OscilloscopeProperties" class stores all values needed to control the oscilloscope.
+#### 1.1 [redpitaya](./redpitaya):
 
-    The "SigGenProperties" class stores general values to generate waveforms.
-    Each waveform has a own class to store specific info.
-    The general values are inherited by the "SigGenProperties" class

-2. Example folder:
+#### 2. [examples](./examples):
 
 Contains "test_mqtt_py.m" to explain basic mqtt transmissions.
 
 
-    1. redpitaya folder:
+#### 2.1 [redpitaya](./examples/redpitaya):
 
-    Collection of redpitaya specific examples.
-    The "analog_read_slow_example.m" explaines the usage of the external pin header to analoge read by ADC.
-    The "Oscilloscope_example.m" show how the "OscilloscopeProperties" class is applied on a RedPitaya.
-    The "SignalGenerator_example.m" show how the "SigGenProperties" class is applied on a RedPitaya.
