 ## Building static libraries
 
+> [!WARNING]
+> It's preferred to build shared libraries than static libraries:
+>
+> * All code in the loadable module must be compiled with C/C++ compiler version and options that are compatible with native AOT static libraries.
+> * It's also not possible to mix multiple native AOT compiled static libraries within the same loadable module.
