 ## Compile-Time Requirements
 The only Linux and Macintosh compile-time requirement of PEB is a GCC-based Qt development bundle version 5.2 or any later version.  
 
-The source code of PEB is not MSVC-compatible and PEB can not be compiled using any MSVC-based Windows version of Qt.   This means that:  
-* PEB Windows binaries can be compiled only by a GCC-based Qt development bundle.
-* Only ```QtWebKit``` can be used by a Windows binary of PEB.
