+// This is [Rust-101](https://www.ralfj.de/projects/rust-101/), a small *work-in-progress*
+// tutorial for the [Rust language](http://www.rust-lang.org/).
+// It is intended to be an interactive, hands-on course: I believe the only way to
 // *really* learn a language is to write code in it, so you should be coding during
-// the course. These documents mainly serve as a guide to the teacher, reminding me
-// what to explain in which order, and making sure I have sample code for all topics
-// I plan to cover. They may also be helpful as an offline resource, but you're on your
-// own then.

+// the course. I am writing this tutorial with a tutorial situation in mind, i.e.,
+// with a teacher being around to guide students through the course and answer
+// questions as they come up. However, I think they may also be useful if you
+// work through them on your own, you will just have to show more initiative yourself:
+// Make sure you actually type some code. It may sound stupid to manually copy code
+// that you could duplicate through the clipboard, but it's actually helpful.
+// If you have questions, check out the "Additional Resources" below. In particular,
+// the IRC channel is filled with awesome people willing to help you! I spent
+// lots of time there ;-)
+// 
 // I will assume basic familiarity with programming, and hence not explain the basic
 // concepts common to most languages. Instead, I will focus on what makes Rust special.
-
+// 
+// Prerequisites
+// -------------
+// 
+// You will need to have Rust installed, of course. It is available for download on
+// [the Rust website](http://www.rust-lang.org/). At this point, I plan to restrict
+// myself to stable Rust, so "Recommended" version is just right.
+// You can find some more installation instructions in
+// [the second chapter of The Book](https://doc.rust-lang.org/stable/book/installing-rust.html).
+// When you are done, running `cargo build` in the root of Rust-101 should successfully compile
+// all the code.
+// 
+// Getting the source
+// ------------------
+// 
+// You are meant to play around with the source code of the course as you go on, so please
+// fetch it from the [git repository](http://www.ralfj.de/git/rust-101.git) (also available
+// [on GitHub](https://github.com/RalfJung/rust-101)).
+// 
+// Course Content
+// --------------
+// 
 // The actual course is in the partXX.rs files. I suggest you get started with
 // [the first part](part00.html), or jump directly to where you left off:
-
+// 
 // * [Part 00](part00.html)
 // * [Part 01](part01.html)
+// * [Part 02](part02.html)
+// * [Part 03](part03.html)
+// * (to be continued)
