+## 0. Install Python
+
+We need Python 3.10 at least installed (it was tested with this version to say the least).
+
+## 1. Build Demucs
+
+First we need to build Demucs
+We will create and a enter a new Python virtual environment in the `demucs\venv` folder.
+
+Navigate to in the `demucs` sub folder, where you need to run these commands:
+1. this will create and a enter a new Python virtual environment: `python -m venv venv`
+2. enter this virtual environment with `venv\Scripts\activate`, it will now show `(venv) ` in front of the prompt
+3. this will install Python requirements for CUDA support (only Windows and Linux) through pip: `pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu116 demucs SoundFile cx-Freeze`, alternative is CPU only `pip3 install torch torchvision torchaudio demucs SoundFile cx-Freeze`
+4. this will build demucs (Windows & Linux): `cxfreeze main.py --target-dir=dist --target-name=demucs-cxfreeze --packages=torch --includes=demucs.htdemucs`
+or without pip3 install torch torchvision torchaudio demucs SoundFile cx-Freeze
+5. this will exit the virtual environment: `deactivate`
+
+You find the `demucs` software now under `demucs\dist`
+
+## 2. Copy _soundfile_data files
+
+Copy the folder `demucs/venv/Lib/site-packages/_soundfile_data` to `demucs/dist/lib/_soundfile_data` (overwrite)
+
+You can now remove the contents of the `demucs\venv` folder as it is no longer needed, about 1 GB
+
+## 3. Bundle ffmpeg and ffprobe with demucs
+
+
+First download the `ffmpeg` and `ffprobe` executables, e.g.:
+
+Windows: https://www.gyan.dev/ffmpeg/builds/ffmpeg-release-essentials.zip
+MacOS: https://evermeet.cx/ffmpeg/ffmpeg-109428-g10a56363a7.zip and https://evermeet.cx/ffmpeg/ffprobe-109428-g10a56363a7.zip
+
+Then copy them to `demuncs\dist`
+
+## 4. Download models
+
+Downloaded models and their corresponding YAML-file should be placed in a directory, and that directory should be passed to Demucs via the `-n` and `--repo` command line arguments.
+
+Models for `htdemucs_ft`:
+
