+This guide is meant to help document how rustc – the Rust compiler – works,
+as well as to help new contributors get involved in rustc development.
 
 There are seven parts to this guide:
 
-1. [Building and debugging `rustc`][p1]: Contains information that should be
-   useful no matter how you are contributing, about building, debugging,
-   profiling, etc.
-2. [Contributing to `rustc`][p2]: Contains information that should be useful
-   no matter how you are contributing, about procedures for contribution, using git
-   and Github, stabilizing features, etc.
-3. [High-Level Compiler Architecture][p3]: Discusses the high-level
-   architecture of the compiler and stages of the compile process.
-4. [Source Code Representation][p4]: Describes the process of taking raw source code from the user and
-   transforming it into various forms that the compiler can work with easily.
-5. [Analysis][p5]: discusses the analyses that the compiler uses to check various
-   properties of the code and inform later stages of the compile process (e.g., type checking).

 ### Constant change

 As such, it has its fair share of codebase churn and technical debt.
