 This assumes you have a working Rust and Go toolchain on the host machine

+1. `rustup toolchain add x86_64-unknown-linux-musl`
 1. Install [`rtf`](https://github.com/linuxkit/rtf): `go install github.com/linuxkit/rtf@latest`
 1. Install rust-script: `cargo install rust-script`
 1. Install `qemu` and `cloud-init-utils` package - or any package that provides `cloud-localds`
 
 It is not required, but the tests run significantly faster if you use `sccache`
 
+You may also use the docker image to run the tests:
+
+```
+docker run -it --rm --device /dev/kvm -v/home/dave/dev/aya-rs/aya:/src -w /src/test ghcr.io/aya-rs/aya-test-rtf:main
+```

 ## Usage
