+# raylib-cpp CMake Example Project
+
+Use this template to build a [raylib-cpp](https://github.com/RobLoach/raylib-cpp) project using [CMake](https://cmake.org).
+
+## Build
+
+To build this project, make sure to have CMake installed locally.
+
+### Desktop
+
+```
+mkdir build
+cmake . --preset Release
+cmake --build build/Release --preset Release
+```
+
+### Web
+
+```
+mkdir build
+emcmake cmake . --preset ReleaseWeb
+emcmake cmake --build build/ReleaseWeb --preset ReleaseWeb
+```
+
+## Run
+
+```
+./build/Release/raylib-cpp-example

+*   It was adapted from the raylib-cpp [core] example - Basic Window
+*   with changes made to allow for compiling with C++ modules
+*   To compile it for PLATFORM_WEB just use the --preset DebugWeb or ReleaseWeb in
