How to try it

Easiest: install Steltic Hub (git clone https://github.com/Steltic/steltic_hub, then windows\Steltic.bat or ./unix/steltic.sh); it installs the modules for you.

On its own (Python 3.10–3.12):

git clone https://github.com/Steltic/steltic_cfs
cd steltic_cfs
python3.12 -m venv .venv        # Windows: py -3.12 -m venv .venv
source .venv/bin/activate       # Windows: .venv\Scripts\Activate.ps1
pip install -e .
steltic-cfs

Install is git clone only; the old PyPI packages are no longer supported.
