+There is another style of doc comment, `//!`, to comment containing items (e.g.
+crates, modules or functions), instead of the items following it. Commonly used
+inside crates root (lib.rs) or modules root (mod.rs):

 When writing doc comments, providing some examples of usage is very, very
 helpful. You’ll notice we’ve used a new macro here: `assert_eq!`. This compares
 two values, and `panic!`s if they’re not equal to each other. It’s very helpful
