The tutorial in the Readme doesnt work for me

[Reydaa]

hello,
I am doing some research on Programming language correction and i found this project of yours which i think is very interesting.
However, i am not quite familiar with C# and i didnt get to see the results of the project. Can you give me a quick tutorial on how to use it. I tried to build the project in Vscode it gives me some errors when building the refazerweb , and also when trying to execute the Readme tutorial it tells me there is some problems with nuget packages or that it does not recognize the IsNullorEmpty fonction. Also, the test does not succeed only 5 or 6 of them, so i am a bit confused as i would really love to test this project.
If you have some explanation or help it would be wonderful.
Thank you very much
