// Welcome to Rust-101
// ===================
-//
+//
// 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. I am writing this tutorial with a tutorial situation in mind, i.e.,
+// the course. I am writing this 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. Just make sure to actually play with the code.
-// If you have any questions, maybe the "Additional Resources" below are useful.
+// 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 ;-)

+// Why Rust?
+// ---------
+//
+// When you got here, I am kind of assuming that you already decided to give Rust at
+// least a look, so that I don't have to do much convincing here ;-) . But just in
+// case, here's why I think Rust is worth learning:<br/>
+// At this time, Rust is a language with a pretty unique set of goals. Rust aims to
+// achieve C++-style control over memory and execution behavior (like, static vs. dynamic
+// dispatch), which makes it possible to construct abstractions that carry no run-time
+// cost. This is combined this with providing the comfort of high-level functional languages
+// and guaranteeing safety (as in, the program will not crash). The vast majority of existing
+// languages sacrificies one of these goals for the other. In particular, the
+// first requirement rules out a garbage collector: Rust can run "mare metal".
+// In fact, Rust rules out more classes of bugs than languages that achieve safety
+// with a GC: Besides dangling pointers and double-free, Rust also prevents issues
+// such as iterator invalidation and race conditions.
+//
+//
// 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.
// [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)).

-// 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:

+// to give you a feeling for Rust's syntax and pervasive mechanisms like pattern matching and traits.
+// Parts 04-?? introduce the heart of the language, the mechanism making it different from anything
+// else out there.
