+## Zig 0.11 can be used as a C/C++ compiler frontend
+
+Zig offers
+[a C/C++ frontend](https://andrewkelley.me/post/zig-cc-powerful-drop-in-replacement-gcc-clang.html) as a drop-in replacement for Clang. It worked fine with Meson up to Zig 0.10. Since 0.11, Zig's
+dynamic linker reports itself as `zig ld`, which wasn't known to Meson. Meson now correctly handles
+Zig's linker.
+
+You can use Zig's frontend via a [machine file](Machine-files.md):
+
+```ini
+[binaries]
+c = ['zig', 'cc']
+cpp = ['zig', 'c++']
+ar = ['zig', 'ar']
+ranlib = ['zig', 'ranlib']
+lib = ['zig', 'lib']
+dlltool = ['zig', 'dlltool']
+```
