+# rFXGen CMake
+
+This allows building [rFXGen](https://raylibtech.itch.io/rfxgen) with [CMake](https://cmake.org).
+
+## Usage
+
+To compile the example, use one of the following dependending on your build target...
+
+### Desktop
+
+Use the following to build for desktop:
+
+``` bash
+cmake -B build
+cmake --build build
+```
+
+### Web
+
+Compiling for the web requires the [Emscripten SDK](https://emscripten.org/docs/getting_started/downloads.html):
+
+``` bash
+mkdir build
+cd build
+emcmake cmake .. -DPLATFORM=Web -DCMAKE_BUILD_TYPE=Release -DCMAKE_EXE_LINKER_FLAGS="-s USE_GLFW=3" -DCMAKE_EXECUTABLE_SUFFIX=".html"
+emmake make
+```
