 It is supposed to work similar to the well-known `dig` command line tool on Linux, with a lot fewer options of course.
 
 ## How to Build/Run it
-To run it, open a command line windows, or bash, navigate to \Samples\MiniDig and run `dotnet restore` and `dotnet run`.

-MiniDig is multi targeted for now, which means, when you use `dotnet run` you have to specify a framework `-f NetCoreApp20` for example.

-On Linux, e.g. running it in Ubuntu, the dotnet SDK currently has bugs to resolve certain things. To build and run it, you might have to publish a self-contained output with `dotnet publish -f NetCoreApp20 --self-contained -r ubuntu-x64` for example.
-
-## Help
-`dotnet run -?` gives you the list of options and commands.
+MiniDig is multi targeted for now, which means, when you use `dotnet run` you have to specify a framework 
+`-f NetCoreApp2.0` or `-f net472` for example.
 
 ## Examples
-`dotnet run google.com ANY` to query for google.com
+`dotnet run -f netcoreapp2.0 google.com ANY` to query for google.com
 
 If nothing else is specified, it uses the DNS server configured for your local network adapter.
 To specify a different server, use the `-s` switch, for example:
 
-`dotnet run -s 8.8.8.8 google.com` to use the public google name server.
+`dotnet run -f netcoreapp2.0 -s 8.8.8.8 google.com` to use the public google name server.
+
+
+`dotnet run -f netcoreapp2.0 -s 127.0.0.1#8600` to also specify a custom port.

 ## Performance Testing
 One subcommand `perf` can be used to run performance tests
