Engine documentation

Hello everyone,

I downloaded the Unreal Engine 4.11.2 from git repository and achieved to compile it properly. Now I want to read the engine documentation that it is on .udn format, I don’t know exactly how open this format. I tried to run UnrealDocTool.exe and Publish-UDN-INT.bat, but I found the same error:

Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a part
of the path ‘E:\UnrealEngineSource\Engine\Documentation\Source\Include\Internat
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileSystemEnumerableIterator1.CommonInit() at System.IO.FileSystemEnumerableIterator1…ctor(String path, String origina
lUserPath, String searchPattern, SearchOption searchOption, SearchResultHandler`
1 resultHandler, Boolean checkHost)
at System.IO.Directory.GetFiles(String path)
at MarkdownSharp.Language.InstInit(String internationalizationFilesDirectory)

at UnrealDocTool.UnrealDocTool.Main(String] args)

Then, how I could open the engine documentation?

Thanks before hand!
