+This action registers QEMU emulators with `binfmt_misc`, so later steps can run
+containers built for another architecture on the GitHub-hosted runner.
+
+```yaml
+name: run-cross-platform-container
+
+on:
+  workflow_dispatch:
+
+jobs:
+  qemu-example:
+    runs-on: ubuntu-latest

+      -
+        name: Run an arm64 container
+        run: docker run --rm --platform linux/arm64 alpine uname -m

+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.
