+Pixel Wars is a programming game where two minimalistic civilizations
+will grow and try to annihilate each other to conquer the Pixel World. 
+But you don't have any real-time control over the action of your units.
+To be victorious, you'll have to code their behaviour in C/C++,
+and pray for a good result.
+
+This repository is the application project, it has severay dependencies :
+Qt5 modules: core gui widgets opengl, glm, SparrowRenderer, and cmake for the compilation
+
+### How to Use it from the precompiled builds (not available yet) :
+- download the latest build (insert links here)
+- unzip it anywhere
+- the PixelWars executable is located in the bin folder
+- you can now code your own Dude's behavior or map generator by
+placing in the respective "behaviors" and "generators" folder your compiled code
+in the form of a shared library, you can find an example in each folder named hello.cpp,
+containing the minimal code, the necessary includes,
+and the command line needed to compile it.
+
+### How to Build it from sources :
+
+download and install git, cmake, Qt5, and a c++ compiler (gcc on Unix or MinGW on Windows)
+
+get all required repositories :
+git clone https://git.epicsparrow.com/epicsparrow/CMakeTemplate.git
+git clone https://git.epicsparrow.com/epicsparrow/SparrowRenderer.git
+git clone https://git.epicsparrow.com/epicsparrow/PixelWars.git
+
+get all required dependencies,
+unzip this archive where you cloned the repositories :
+https://epicsparrow.com/media/libs/glm.zip
+
+you can now compile the sparrow renderer :
+- go in the SparrowRenderer folder
+- mkdir build
+- cd build
+- cmake ..
+- make
+
+after that, you'll be able to compile PixelWars :
+(same procedure)
+- go in the PixelWars folder
+- mkdir build
+- cd build
+- cmake ..
+- make
+
+That's it ! The PixelWars executable should have been generated in the build folder
