+# Starting your raylib project with Zig (0.16.0)
+
+## How to compile and run it
+
+To compile the project:
+
+```sh
+zig build
+```
+
+To run the project:
+
+```sh
+zig build run
+```
+
+## Compile with different optimization
+
+To change from debug to release build you can do it with the `-Doptimze=` flag.
+
+```
+Debug
+ReleaseSafe
+ReleaseFast
+ReleaseSmall
+```
+
+## Choose a different platform
+
+To compile with a different platform you can use the `-Dplatform=` flag.
+Here all the options:
+
+```
+glfw
+rgfw
+sdl
+sdl2
+sdl3
+memory
+win32
+drm
+android
+```
+
+In this example the platform `sdl` and `sdl2` are not supported
+
+Important for the android platform you also have to compile for the right target
+
+## Compile for a different target
+
+To compile for a different [target](https://ziglang.org/download/0.16.0/release-notes.html#Support-Table) you can use the `-Dtarget=` flag.
+Not all targets are supported
+
+## Example: Compile for web and run it
+
+To compile for the web we use emscripten and you run it like that:
+
+```sh
+zig build -Dtarget=wasm32-emscripten
+```
+
+To run it we do:
+
+```sh
+zig build run -Dtarget=wasm32-emscripten
+```
+
+And to make a relase build we do:
+
+```sh
+zig build -Dtarget=wasm32-emscripten -Doptimize=ReleaseFast
+```
+
+If we want to use rgfw for the web build we could do:
+
+```sh
+zig build -Dplatform=rgfw -Dtarget=wasm32-emscripten -Doptimize=ReleaseFast
+```
+
+## Compiling the Zig code? Just add `-Dzig` and try out zig ;)
+
+## More Resources
+
+See [Zig Build System](https://ziglang.org/learn/build-system/)
