NuGet.org now showsREADME.md file if you include it into the package.

https://devblogs.microsoft.com/nuget/add-a-readme-to-your-nuget-package/

Problem is our README is in.rst format. The options are:

1. newREADME.md tailored to .NET
2. rewrite our.rst into.md

I prefer option 1 because our README has info for both embedding into Python and into .NET, but NuGet package is tailored only for embedding into .NET.
