+// Prerequisites
+// -------------
+//
+// You will need to have Rust installed, of course. It is available for download on

+// 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.

+// 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:
