 Your NuGet package needs to respect a few constraints in order to be listed in the curated list:
 
 - It must have non-preview versions (e.g `1.0.0` but not `1.0.0-preview.1`)
-- It must provide `.NETStandard2.0` assemblies as part of its package
+- It must provide at least `.NETStandard2.0` (and optionally `.NETStandard2.1`) assemblies as part of its package
 
 You can send a PR to this repository to modify the [registry.json](registry.json) file (don't forget to maintain the alphabetical order)
 
 You also need to **specify the lowest version of your package that has support for `.NETStandard2.0`** upward so that other packages depending on your package have a chance to work with.
 
 Beware that **all transitive dependencies of the package** must be **explicitly listed** in the registry as well.
