+// 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)).
