WebRender Hacking Setup

(not a tutorial for the innards, just the environment)

If you need help or have questions about any of this, please ask on #servo on irc.mozilla.org.

Rust

WebRender is written in the Rust programming language. There are a number of great resources for learning Rust, but you probably want to start with "The Book" and perhaps work through Rust by Example.

Setup

This document assumes that you have your preferred way of cloning git repositories from github, and that you have your platform's native compiler toolchain installed (e.g., Visual Studio 2015 on Windows).
