 # pcb2gcodeGUI
-A simple GUI for pcb2gcode. 
-The minimum required Qt's version is 5.0.2.
-After building it, download pcb2gcode
-from https://github.com/pcb2gcode/pcb2gcode/releases
-or follow the instructions in the [README](https://github.com/pcb2gcode/pcb2gcode/blob/master/README.md) to build
-the latest git version, then copy the pcb2gcode binary in the same folder of pcb2gcodeGUI.
+A GUI for [pcb2gcode](https://github.com/pcb2gcode/pcb2gcode).
 
 ## Build
-### Build on Debian Jessie/Sid, Ubuntu Trusty/Utopic/Vivid

 ### Build on Windows
-The easiest way to build pcb2gcodeGUI on windows is by downloading
-the Qt SDK from here http://www.qt.io/download-open-source/ and
-building it within Qt Creator. After that, download a pcb2gcode
-Windows build and put it in the same folder of the pcb2gcodeGUI
-binary
+Note that pre-built binaries for Windows are available in the [release page](https://github.com/pcb2gcode/pcb2gcodeGUI/releases).
+
+To build pcb2gcodeGUI on Windows download the [Qt SDK](http://www.qt.io/download-open-source/)
+and install it, then open pcb2gcodeGUI.pro inside Qt creator, select "Release" and build it.
+
+You can also build pcb2gcodeGUI statically with [MSYS2](http://sourceforge.net/projects/msys2/):
+ * Download MSYS2
+ * Install the required build packages (follow the instructions for pcb2gcode)
+ * `pacman -S mingw-w64-i686-qt5-static` (or `pacman -S mingw-w64-x86_64-qt5-static` if you want a 64-bit binary)
+ * `git clone https://github.com/pcb2gcode/pcb2gcodeGUI.git`
+ * `cd pcb2gcodeGUI/`
+ * `/mingw32/qt5-static/bin/qmake.exe` (or `/mingw64/qt5-static/bin/qmake.exe` for the 64-bit binary)
+ * `make`
+ 
+Then copy pcb2gcodeGUI.exe and a pcb2gcode binary (download it from the [release page](https://github.com/pcb2gcode/pcb2gcode/releases)
+or [build it](https://github.com/pcb2gcode/pcb2gcode/blob/master/README.md)) in the same folder.
