The GHC wiki says you need Sphinx to build docs,

            https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Tools

and refers to the Preparation doc for how to install Sphinx

https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation

But the Windows sub-page of Preparation does not say how to install Sphinx.

Question: how does one install Sphinx on Windows?  The sphinx-doc home page mutters about ‘pip’, but I’ve never used that.  Does anyone have instructions?

Thanks
