+> [!WARNING]
+> This feature is still in development, and the API may change in future releases.
+> Your contribution is needed to help us improve the compatibility and usability
+> of C++20 modules in FTXUI. If you encounter any issues or have suggestions,
+> please open an issue.
+
+FTXUI provides an experimental support for [C++20
+modules](https://en.cppreference.com/w/cpp/language/modules) to improve 
+compilation times and code organization. The existing API has a module 
+corresponding to each header.
+
+**Example with CMake and Ninja**
+
+
+```cpp
+import ftxui;
+
+int main() {
+  auto screen = ftxui::ScreenInteractive::TerminalOutput();
+  auto button = ftxui::Button("Click me", screen.QuitClosure());
+  screen.Loop(button);
+  return 0;
+}
+```
+
+```sh
+cmake \
+    -DCMAKE_GENERATOR=Ninja \
+    -DFTXUI_BUILD_MODULES=ON \
+    ..
+
+ninja
+```
+> [!NOTE]
+> To use modules, you need a C++20 compatible compiler, CMake version 3.20 or
+> higher, and use a compatible generator like Ninja. Note that Makefile
+> generators **do not support modules**.
+
+### Module list
+
+The modules directly reference the corresponding header, or a group of related
+headers to provide a more convenient interface. The following modules 
+are available:
