-There is two approaches that can be adopted: A legacy approach and a modern
-approach. Both of them are supported.
+In order to use the SDL2 CMake modules, we have to clone this repository in a
+sud-directory `cmake/sdl2` in our project as follows:
+
+```sh
+cd <PROJECT_DIR>
+git clone https://gitlab.com/aminosbh/sdl2-cmake-modules.git cmake/sdl2
+rm -rf cmake/sdl2/.git
+```
+
+Or if we are using git for our project, we can add this repository as a
+submodule as follows:
+
+```sh
+cd <PROJECT_DIR>
+git submodule add https://gitlab.com/aminosbh/sdl2-cmake-modules.git cmake/sdl2
+git commit -m "Add SDL2 CMake modules"
+```
+
+Then we should specify the modules path in the main CMakeLists.txt file like
+the following:
+
+```cmake
+list(APPEND CMAKE_MODULE_PATH ${CMAKE_CURRENT_SOURCE_DIR}/cmake/sdl2)
+```
+
+Finally, we can use the SDL2 modules. There is two approaches that can be
+adopted: A legacy approach and a modern approach. Both of them are supported.
