Livingdoc error

Hi all,

When I try to run livingdoc generator I am getting the following error: 

The framework 'Microsoft.NETCore.App', version '5.0.0' was not found.
  - The following frameworks were found:
      3.1.25 at [/usr/local/share/dotnet/x64/shared/Microsoft.NETCore.App]

In the requirement spec it is stated that .net core 3.1 is the minimum. Is this still correct?
