+##### Multi-Architecture
+
+The Docker images support multi-architecture: `linux/amd64`, `linux/arm64` and `linux/arm/v7`.
+
+On ARM machines, if you get this error when running a `psu` Docker image:
+```
+standard_init_linux.go:228: exec user process caused: exec format error
+```
+
+You need to install `linux/amd64` QEMU binary, like this:
+```bash
+docker run --privileged --rm tonistiigi/binfmt --install linux/amd64
+```
+Then run your `psu` Docker image again and it should work 🤞
+
+And if you want to uninstall this QEMU binary, run this command:
+```bash
+docker run --privileged --rm tonistiigi/binfmt --uninstall linux/amd64
+```

 For testing/debugging, you can use this Docker image in interactive mode, to run any commands inside the container:
