-# DUDE-Star
+# DUDE-Shield
 Software to RX/TX D-STAR, DMR, Fusion YSF/FCS, NXDN, P25, M17, and IAX (AllStar client) over UDP
 
+This software is a fork based on initial porject named DUDE-Star, available on github : 
+https://github.com/nostar/dudestar
+
 This software connects to D-STAR, Fusion, NXDN, P25, M17 reflectors and AllStar nodes (as an IAX2 client) over UDP.  It is compatible with all of the AMBE3000 based USB devices out there (ThumbDV, DVstick 30, DVSI, etc). It includes software decoding and encoding support, using experimental open source IMBE/AMBE vocoder software.  This software is open source and uses the cross platform C++ library called Qt.  It will build and run on Linux, Windows, and Mac OSX.
 
 This software makes use of software from a number of other open source software projects, including MMDVMHost, MMDVM_CM, XLXD, DSDcc, MBELIB, op25 (GNU Radio), mvoice, and others. Not only is software from these projects being used directly, but learning about the various network protocols and encoding/decoding of the various protocols was only possible thanks to the authors of all of these software projects.

 Add DTMF commands like \*3node, \*1node, \*70, etc in the IAX DTMF box and hit send to send the DTMF string.  The asterisk (*) character is already added on the Droidstar app, so only input the numeric portion of the command (70 instead of *70, etc). Details on various commands can be found at the AllStar wiki and others.
 
+# Compiling on Windows
+The best way to build Dude Shield on windows is to install in order :
+- Microsoft Visual Studio Community Edition
+  https://visualstudio.microsoft.com/fr/
+
+- QT Installer
+  https://www.qt.io/download-qt-installer
+
+Once each software are installed, you can open DudeShield Project with QtCreator and build the solution
+
+Release are also available on github with a 64bit installer for windows.
+
+# Compiling on MacOS
+
+you need before Xcode from Apple Store to be able build binaries. 
+Then QT Installer https://www.qt.io/download-qt-installer
