+# Linux Tests
+This repository contains utilities for running integration tests for Linux guests under Machina.
+
+## Build
+First install rust (follow the instructions of the rustup tool):
+```
+$ curl https://sh.rustup.rs -sSf | sh
+$ source ~/.cargo/env
+```
+
+Next we add some new targets for cross-compiling and static linking. Rust supports statically linking libc by replacing the usual gnu libc with musl (see [The Rust Book: Advanced Linking](https://doc.rust-lang.org/1.9.0/book/advanced-linking.html)).
+```
+$ rustup target add x86_64-unknown-linux-musl
+$ rustup target add aarch64-unknown-linux-musl
+```
+
+Lastly, run the build script for your desired architecture. This will invoke cargo for you as well as create an ext2 image in out/.
+```
+$ ./build.sh {arm64|x64}
+```
