 # How to run 
 
-Notes: dotnet run supports passing arguments to app after -- symbols (https://docs.microsoft.com/en-us/dotnet/articles/core/tools/dotnet-run) - example: **dotnet run -- -h** will show help for app
+Depending on the platform, the name of the generated executables will vary. On Linux, it is just "client" or "server", on Windows it is "Client.exe" and "Server.exe". In the following, we use the abbreviated form "Client" and "Server".
 
 - build 
 - go to folder (Client/Server) 
-- run with specifying of correct parameters **dotnet run -tr:tcp -pr:multiplexed**, **dotnet run -help** (later, after migration to csproj and latest SDK will be possibility to use more usable form **dotnet run -- arguments**)
-
-#Notes
-- Possible adding additional platforms after stabilization of .NET Core (runtimes, platforms (Red Hat Linux, OpenSuse, etc.) 
+- run the generated executables: server first, then client from a second console
 
 #Known issues
 - In trace logging mode you can see some not important internal exceptions
 
 # Running of samples 
-Please install Thrift C# .NET Core library or copy sources and build them to correcly build and run samples 
+On machines that do not have the SDK installed, you need to install the NET Core runtime first. The SDK is only needed to build programs, otherwise the runtime is sufficient.
