+This repository contains the source code for the _Writing an OS in Rust_ series at [os.phil-opp.com](https://os.phil-opp.com).
 
 ## Building
-You need to have `nasm`, `grub-mkrescue`, `mformat` (included in `mtools`), `xorriso`, `qemu`, a nightly Rust compiler, and [xargo] installed. Then you can run it using `make run`.
+You need a nightly Rust compiler and the `cargo-xbuild` and `bootimage` tools. You can install the tools by executing the following command:
 
-[xargo]: https://github.com/japaric/xargo
+```
+cargo install cargo-xbuild bootimage
+```
 
-Please file an issue if you run into any problems.
+Afterwards you can invoke `bootimage build` to produce a bootable disk image. Please file an issue if you run into any problems.
+
+To run the image in [QEMU], you can execute `bootimage run`. Note that you need to have QEMU installed.
