+## Visual Studio 2022 backend
+
+As Visual Studio 2022 is released recently, it's time to support the
+new version in Meson. This mainly includes the new "v143" platform tools.
+
+The usage is similar to other backends. For example
+```meson
+meson setup builddir --backend=vs2022
+```
+will configure "builddir" for projects compatible with Visual Studio 2022.
