+# SDLRenderer3
+
+This example takes from `example_sdlgpu3`. We need to generate bindings for SDLRenderer3 backend because they are not native to `cimgui`. Then you can add the compiled library for linking in your application.
+
+For the generation phase from cmake you need LuaJIT to be present.
+
+## Building
+
+From the build directory of your choice:
+
+`cmake path_to_example_sdlgpu3`
+
+Then simply run:
+
+`make`
+
