 // 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.,
-// 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.

 // concepts common to most languages. Instead, I will focus on what makes Rust special.
 //
-// Prerequisites
-// -------------
-//
+// 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 with the comfort of high-level functional languages and guaranteed
+// safety (as in, the program will not crash in uncontrolled ways). The vast majority of existing
+// languages sacrifices control for safety (for example, by enforcing the usage of
+// a garbage collector) or vice versa. Rust can run without dynamic allocation (i.e., without
+// a heap), and even without an operating system. In fact, Rust rules out more classes of bugs
+// than languages that achieve safety with a garbage collector: Besides dangling pointers and
+// double-free, Rust also prevents issues such as iterator invalidation and data races.
+// 
+// 
+// Getting started
+// ---------------
+// 
 // 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 Rust website](https://www.rust-lang.org/). Make sure you get at least version 1.2.
+// More detailed installation instructions are provided 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)).
-//
+// This will also install `cargo`, the tool responsible for building rust projects (or *crates*).
+// 
+// Next, fetch the Rust-101 source code from the [git repository](https://www.ralfj.de/git/rust-101.git)
+// (also available [on GitHub](https://github.com/RalfJung/rust-101), and as a
+// [zip archive](https://github.com/RalfJung/rust-101/archive/master.zip) in case you don't have git installed).
+// 
+// There is a workspace prepared for you in the `workspace` folder. I suggest you copy this
+// folder somewhere else. Try `cargo build` in that new folder to check that compiling your workspace succeeds.
+// (You can also execute it with `cargo run`, but you'll need to do some work before this will succeed.)
+
 // 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:
+// Open `your-workspace/src/part00.rs` in your favorite editor, and follow the link below for
+// the explanations and exercises. You are ready to start. Have fun!
