// 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.

// 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). The vast majority of existing
-// languages sacrifices one of these goals for the other. In particular, the
-// first requirement rules out a garbage collector: Rust can run "bare 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 data races.
+// 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. Finally,
+// it cleans up behind you, and deallocates resources (memory, but also file descriptors and really
+// anything) when you don't need them anymore.
//
//
// 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/). You should go for either the "stable"
-// or the "beta" channel. More detailed installation instructions are provided in
-// [the second chapter of The Book](https://doc.rust-lang.org/stable/book/installing-rust.html).
+// [the Rust website](https://www.rust-lang.org/). Make sure you get at least version 1.3.
+// More detailed installation instructions are provided in
+// [The Book](https://doc.rust-lang.org/stable/book/).
// 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](http://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 - that will make it much easier to later update the course without
-// overwriting your changes. 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.)
-//
-// If you later want to update the course, do `git pull` (or re-download the zip archive).
-// Then copy the files from `workspace/src/` to your workspace that you did not yet work on. Definitely
-// copy `main.rs` to make sure all the new files are actually compiled. (Of course you can also
-// copy the rest, but that would replace all your hard work by the original files with all the holes!)
+//
+// Next, we have to prepare a workspace for you to conduct your Rust-101 work in, so that you don't
+// have to start with an empty file. The easiest way is to
+// [download the workspace](https://www.ralfj.de/projects/rust-101/workspace.zip)
+// matching the online tutorial. 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 does
+// anything useful.)
+//
+// Alternatively, you can build the workspace from source by fetching the
+// [git repository](https://www.ralfj.de/git/rust-101.git) and running `make workspace`.
