-// [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)).
-//
+// [the Rust website](http://www.rust-lang.org/). Make sure you get at least version 1.2
+// (at the time of writing, that's the current beta release). More detailed installation
+// instructions are provided in [the second chapter of The Book](https://doc.rust-lang.org/stable/book/installing-rust.html).
+// 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!)
