+### **C++ Modules Support**
+To build and use **C++20 Modules**, ensure the following prerequisites are met:
+
+#### **1. Compiler Support**
+You need a compiler that supports **C++20 Modules**. The following versions are required:
+- **GCC 11+** (Recommended: **GCC 14.2.0+**)
+- **Clang 10+**
+- **MSVC 19.30+ (Visual Studio 2022+)**
+
+To check your compiler version, run:
+```sh
+g++ --version
+```
+Ensure it outputs GCC 11+, preferably GCC 14.2.0 or later. You can check if your compiler supports CPP Modules [on this page](https://en.cppreference.com/w/cpp/compiler_support/20)
