In this recipe, you learned to set up the Servo browser engine and run websites in the engine. Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, and Android.
Servo is built with Cargo and it uses Mozilla's Mach tools to orchestrate the build and other tasks. We run a URL in Servo with ./mach run https://www.google.com.
There are lots of Mach commands we can use for building and hacking. You can list them with ./mach --help.
