To get started download and install miniconda, then use the conda command to create an environment called seahorce based on the seahorce.yml file in the repository:
conda env create -f seahorce.yml
Activate that environment, if not already,
conda activate seahorce
Now launch an instance of jupyterlab from the command line:
jupyter lab
A browser window will start up, and you can navigate to the notebooks you want to work with.
