We recommend to start from Miniforge for the MSS installation.

Miniforge comes with the popular conda-forge channel preconfigured, but you can modify the configuration to use any channel you like.

The next steps are to check for an existing Miniforge Installation.

If possible we try to:

install Miniforge including mamba then Create a mssenv then Install MSS.
