 The graphics engine is implemented over a RHI-like (Rendering Hardware-Interface-like); supporting multi-API(s) (OpenGL, OpenGL ES3, Vulkan, etc). EKG implements some object-state based concepts, like in the initialization process and sampler creation, due the Khronos API high-performance Vulkan support.

-# Linking & Building
+# Linking
 
-For first, EKG does not need be implement only on SDL application, but there is only one OS platform implemented: SDL2;
-you are able to integrate GLFW, Win32, Wayland, or any window layer library, [contributing here](/include/os).
+* Warning: Instead of compiling everything and linking all required libs (Vulkan and OpenGL); soon EKG must implement a second native library code to separate GPU APIs implementations 
+but for now EKG requires link the platform and API libraries together. 
 
-The EKG supports natively two APIs: OpenGL, and ~~Vulkan~~. Vulkan is not supported yet, but soon;
-you are able to integrate Metal or DirectX 11 and DirectX 12, [contributing here](/include/os).
+First [download](https://github.com/vokegpu/ekg-ui-library/releases) the latest release and [FreeType2](https://freetype.org/), also order of the linker is important too, be sure you link EKG before the required libs.   
+Let see for SDL2 and OpenGL with GLEW.
 
-Basically, this way is deprecated but is usable. Instead of compiling everything and linking all required libs (Vulkan and OpenGL).  
-Soon EKG must implement a second native library code to separate GPU APIs implementations,
+```bash
+# cmake
+add_executable(your-project-name ekg SDL2main SDL2 freetype glew32)
 
-Be sure you compile together all these three libs:  
-[GLEW](https://glew.sourceforge.net/)/[Vulkan](https://www.vulkan.org/)/GLES3, [SDL2](https://www.libsdl.org/), and [Freetype](https://freetype.org/).
+# make
+cxx ... -lekg -lSDL2main -lSDL2 -lfreetype -lglew32
+```
 
-The order of the linker is important too, be sure you link EKG before the required libs.
-[If you are on Android NDK](https://github.com/vokegpu/pompom), please replace GLEW with GLES3.

+EKG used some std 17 features, so the minimum std version is 17, note: you must use [CMake](https://cmake.org/download/) with [Ninja](https://github.com/ninja-build/ninja) to generate makefiles. 
+
+If you can not compile because of `freetype not found`, insert flag `-DEKG_LINUX_NOT_FOUND_FREETYPE=1`; the CMake build file will force an include.
+
+If you want to build the test programs insert `-DEKG_ENABLE_TEST=1`.

+cmake -S . -B ./cmake-build-debug -G Ninja
