+Operating systems and hardware architectures are supported on a best-effort basis, and patches to add additional OS/arch support are welcome. Building for Linux (`x86_64`), macOS (`aarch64`), and Windows (`x86_64` via `mingw64`) is directly tested by CI.
 
 The command-line programs `nc`, `ocspcheck`, and `openssl` are not built by default, and building them when targeting Windows is not supported. Building the command-line programs may be enabled by specifing the `-Dbuild-apps` option to `zig build`
