+![Jawbreaker](https://raw.github.com/mossmann/hackrf/master/doc/jawbreaker.jpeg)
+
+How to build host software on Windows:
+prerequisite for cygwin or mingw:
+* cmake-2.8.10.2 or more see http://www.cmake.org/cmake/resources/software.html
+* libusbx-1.0.14 or more see http://sourceforge.net/projects/libusbx/files/latest/download?source=files
+* Install Windows driver for HackRF hardware or use Zadig see http://sourceforge.net/projects/libwdi/files/zadig
+  - If you want to use Zadig  select HackRF USB device and just install/replace it with WinUSB driver.
+* Build libhackrf before to build this library, see host/libhackrf/Readme.md.
+  
+For Cygwin:
+cmake -G "Unix Makefiles" -DCMAKE_LEGACY_CYGWIN_WIN32=1 -DLIBUSB_INCLUDE_DIR=/usr/local/include/libusb-1.0/
+make
+make install
+
+For Mingw:
+#normal version
+cmake -G "MSYS Makefiles" -DLIBUSB_INCLUDE_DIR=/usr/local/include/libusb-1.0/
+#debug version
+cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Debug -DLIBUSB_INCLUDE_DIR=/usr/local/include/libusb-1.0/
+make
+make install
+
+How to build host software on Linux:
+cmake ./
+make
+make install

+   a compiled-in constant, such as set a value from `optarg', set the
