A working python 3 installation is required (versions >=3.7 are possible).
For the packaged versions, the following commands have to be executed in the terminal:
conda install -c mcocdawc chemcoord
pip install chemcoord
For the up to date development version (experimental):
git clone https://github.com/mcocdawc/chemcoord.git cd chemcoord pip install .
Neither installation nor running the module are tested on windows. To the best of my knowledge it should work there as well. Just use the same steps as for UNIX.
