+Zserio C++17 generator supports the following platforms:
+
+- 64-bit Linux
+- 32-bit Linux
+- 64-bit Windows
+
+## Supported Compilers
+
+Zserio C++17 generator supports the following C++ compilers:
+
+- g++ 11.4.0
+- clang 14.0.0
+- clang 18.1.3
+- MinGW 11.2.0
+- MSVC 2022
+
+Although newer C++ compilers are not tested, they should work as well as long as they are backward compatible.
