 That’s all there is to it. Comments are not particularly complicated.

-## Documentation comments

-However, Rust has another kind of comment: a documentation comment. These
-comments don’t affect the way that the code works, but they do work with Rust’s
-tools. More specifically, the `rustdoc` tool that comes with Rust reads
-documentation comments and produces HTML documentation from them.
-
-Documentation comments use an extra slash:
-
-```rust

-fn foo() {
-}

-/// We also can use
-/// multiple comments here too,

-fn bar() {
-}
-```
-
-This comment would then be interpreted by `rustdoc` as documenting the thing
-that follows it: `foo()` and `bar()`.

-Because documentation comments have semantic meaning to `rustdoc`, the compiler
-will pay attention to the placement of your documentation comments. For
-example, a program with only this:
-
-```rust,ignore
-/// What am I documenting?
