 Python 3 Blue Box DTMF Tone Generator
 ===================
 
-Really simple, functional tone generator
+Modernized python blue box
 
 **How it works**
 
-Just type on a sequence of numbers/commands and press enter, your computer will play it back for you!
+You can run this in interactive mode, or from a file, pipe, stdin, etc.
 
 **Requirements**
 
-- PyAudio https://people.csail.mit.edu/hubert/pyaudio/
+- Python 3 (tested on 3.9 - 3.11)
 
-```pip3 install pyaudio```
+**Installation**
 
-For OSX you need port audio, which you can install from homebrew:
-
-```brew install portaudio```
+```
+git clone https://github.com/zeyus/Python3BlueBox.git
+cd PythonBlueBox
+pip install -r requirements.txt
+```
 
-For linux or windows, see your package manager, google it or visit here:
+**Usage**
 
-http://www.portaudio.com/download.html
+```
+./bluebox.py -h
+```
 
-**Usage**
+**Examples**
 
 ```
-./PythonBlueBox.py
+./bluebox.py -i
 ```
 
-You'll see the '>>>' prompt. 
-
-```>>> U12345O12345```
-
-You can use the 'U' to switch to user tones or 'O' to switch to operator tones
-
-The current tone mapping works as follows:
-
-```python
-user_tones = {
-    '1',
-    '2',
-    '3',
-    'A',
-    '4',
-    '5',
-    '6',
-    'B',
-    '7',
-    '8',
-    '9',
-    'C',
-    '*',
-    '0',
-    '#',
-    'D',
-}
-op_tones = {
-    '1',
-    '2',
-    '3',
-    '4',
-    '5',
-    '6',
-    '7',
-    '8',
-    '9',
-    '0',  # 0 or "10"
-    'A',  # 0 or "10"
-    'B',  # 11 or ST3
-    'C',  # 12 or ST2
-    'D',  # KP
-    'E',  # KP2
-    'F',  # ST
-}
 ```
+./bluebox.py 123456789
+```
+
+
+
+**Development**
+
+Development of different MF implementations and audio backends is extremely easy now.  Just create a new class that inherits from the MF class, and register it.
+Same thing for audio backends.
+
+Currently there are two MF implementations (DTMF and MF), and two audio backends (PyAudio and Dummy).
