+# Boost Libraries using Zig build-system
 
 [Boost Libraries](https://boost.io) using `build.zig`.
 
 Replacing the [CMake](https://cmake.org/) and [B2](https://www.bfgroup.xyz/b2/) build system.
 
+
+> [!IMPORTANT]
+> For C++ projects, `zig c++` uses llvm-libunwind + llvm-libc++ (static-linking) by default.
+> Except, for MSVC target (`-nostdlib++`).
