 # Installation
 
-## Python
+## Requirements
 
-You need python 3 with the tensorflow library. We will set up a virtual environment to not mess up with the system.
-To do that you will need [virtualenv](https://virtualenv.pypa.io/en/stable/) and
-[virtualenvwrapper](https://virtualenvwrapper.readthedocs.io/en/latest/).
+- MKVToolnix (at least the CLI utils)
+- Python >= 3.8
 
-One way to do it, in the correct directory (the project's one), enter the commands:
+## Setup
+
+This project requires at least Python 3.8, and using a virtual environment is strongly recommended.
+To install the dependencies, execute in the project directory :
 ```bash
-$ python3 -m venv env     # create the virtual envireonment, do it once
-$ source env/bin/activate # use the virtual envireonement
-
-# Here goes the install commands
-$ pip install --upgrade tensorflow
-$ pip install numpy scipy
-$ pip install scikit-learn
-$ pip install pillow
-$ pip install h5py
-$ pip install keras
-
-$ deactivate              # quit the virtual envireonment
+$ python -m venv env     # create the virtual environment, do it once
+$ source env/bin/activate # use the virtual environement
+
+# Install the Demucs (vocal separation tool)
+$ pip install -U demucs
+
+# To exit the virtual environment
+$ deactivate              
 ```
 
-Or, an other way to do it:
+# Use
 
+To extract .wav audio from all MKVs in a folder :
 ```bash
-$ mkvirtualenv keras_tf -p python3  # create the virtual envireonment, do it once
-$ workon keras_tf                   # use the virtual envireonement
-
-# Here goes the install commands
-$ pip install --upgrade tensorflow
-$ pip install numpy scipy
-$ pip install scikit-learn
-$ pip install pillow
-$ pip install h5py
-$ pip install keras
-
-# don't know how to quit, find it yourself
+$ ./extractWav.sh source_folder output_folder
 ```
 
-Or easier, install them directly without virtual environment.
+To separate vocals from instruments in an audio file :
+```bash
+demucs --two-stems=vocal -o output_folder audio_file.wav
+```
