| | FIXME => Move this section somewhere else? |
| | |
| | * Use ''conda install'' and what is described in [[https://github.com/conda/menuinst/issues/246|Easily creating shortcuts with the powershell_shortcut_miniconda and console_shortcut_miniconda packages, and can this be replicated with menuinst ?]] |
| | |
| | * Can theoretically be done with [[https://conda.github.io/menuinst/|menuinst]] |
