 Note: To use the above installed version of MHKiT-Python users must activate the `mhkit-env` environment each time, using `conda activate
 mhkit-env` in each new shell/terminal to use MHKiT.
 To avoid this, users can install MHKiT into their base conda environment, but this is not
 recommended as it may cause dependency conflicts with other software.

 The conda-forge option mirrors how users install MHKiT via `conda install -c conda-forge mhkit`, ensuring all dependencies come from the conda-forge channel. The `--no-deps` flag prevents pip from resolving dependencies, relying entirely on the conda-forge packages for dependencies. The conda-forge build and deployment happens in separate repository: [https://github.com/conda-forge/mhkit-feedstock] which is updated with each MHKiT release.
