+**Horizon-OC-Monitor is deprecated.** If you want to compile it anyway, create a `lib` folder and clone Atmosphere-libs and libultrahand into it:
+
+```bash
+mkdir lib
+git clone https://github.com/Atmosphere-NX/Atmosphere-libs lib/Atmosphere-libs
+git clone https://github.com/ppkantorski/libultrahand lib/libultrahand
+```
