I still don't think I'm understanding you. Are you asking how to edit the ServUO.exe? If so, you just edit the files contained within the "server" folder provided on the Git page (using Notepad++, Visual Studio, SharpeDevelop, etc), and simply recompile it into a new ServUO.exe.
If that also isn't what you're asking, then you may have rephrase the question or use a different translation software.
