+# Simple C++ Setup.
+
+This repository contains a very simple C++ setup using CMake to build, and CTest
+to test it.
+
+
+To build: `mkdir build && cd build && cmake .. && make`
+
+To test: `cd build && ctest`
+
+## But why ?
+
+Because we prefer code over builds.
+
+I've seen many people simply not knowing where to start. Or just writing
+horribles makefiles (To be honest, nobody knows how to cleanly write a simple
+makefile). So I made this simple setup to allows anyone to freely copy the setup
+to start coding, and not start fighting with build systems.
+
+Enjoy!
