 \page using_modules Using D++ with C++ modules
 
+\include{doc} modules_warn.dox
+
 D++ is offered as a C++ module, which offers improved compile times over a traditional header.
 
 In order to enable support, you must use C++20 (or later) with any module-supporting compiler. To activate the feature, pass the `DPP_MODULES` flag to CMake. Ensure that the generated build system supports modules (for CMake, this is usually Ninja; note CMake does not currently support modules with Makefile).
