If you want to contribute, we recommend cloning the repository, setup a conda environmant and installing the package in development mode, e.g.

git clone https://github.com/climate-service-center/index_calculator
cd index_calculator
conda env create -f ci/requirements/environment.yml
conda activate xcalc-tests
pip install -e . --no-deps

This will install the package but you can still edit it and you don't need the package in your PYTHONPATH
