+This action registers QEMU emulators with `binfmt_misc`, so later steps can run
+containers built for another architecture on the GitHub-hosted runner.

+```
+
+The command above prints `aarch64` even though the job itself is running on
+`ubuntu-latest`.
+
+> [!TIP]
+> `setup-qemu-action` enables user-mode emulation for registered platforms. It
+> does not install `qemu-system-*` tools or add `qemu-*` binaries to your PATH.
+
+> [!NOTE]
+> If you are using [`docker/setup-buildx-action`](https://github.com/docker/setup-buildx-action),
+> this action should come before it:
+> 
+> ```yaml
+>     -
