“Dobule quoted”. ‘Single quoted’.

This should NOT be ‘code‘ in Markdown.

Example of vebatim:

`Hi, world.`  
`A “quote”.`  
`Second line.`
`Last line.`  

Another example of verbatim, with ticks/quotes:

Example of a defmodule:

```racket
 (require racket/string)
```

Example of a defproc:

```racket
(make-string k [char]) -> string?
  k : exact-nonnegative-integer? 
  char : char? = #\nul           
```

Returns a new mutable string of length `k` where each position in the
string is initialized with the character `char`

Blah blah `(or/c string? bytes?)`.

```
