+## SDR++, The bloat-free SDR software.
+SDR++ is a cross-platform and open source SDR software with the aim of being bloat free and simple to use.
+
+# Current Features
+* Uses SoapySDR for wide hardware support
+* Hardware accelerated graphics (OpenGL + ImGui)
+* SIMD accelerated DSP (parts of the DSP are still missing)
+* Cross-platform
+* Full waterfall update when possible. Makes browsing signals easier and more pleasant
+
+# Comming soon
+* Multi-VFO
+* Plugins
+* Digital demodulators and decoders
+
+## Building on Windows
+# Requirements
+* cmake
+* vcpkg (for the packages listed below)
+* fftw3
+* portaudio
+* glfw
+* glew
+* PothosSDR (for libvolk and SoapySDR)
+
+```
+mkdir build
+cd build
+cmake .. "-DCMAKE_TOOLCHAIN_FILE=C:/Users/Alex/vcpkg/scripts/buildsystems/vcpkg.cmake" -G "Visual Studio 15 2017 Win64"

+```
+
+## Building on Linux
+comming soon :)
+
+## Building on OSX
+comming soon as well :)
+
+## Contributing
+Feel free to issue pull request and report bugs via the github issues.
+I will soon publish a contributing.md listing the code style to use.
