# Class documentation

Here is a basic class documentation example:

/// Class description
class Student {

    // Member description
    var name: String
    
    /// Method description
    ///
    /// - parameter content:   parameter description
    ///
    /// - returns: return value description
    func say(content: String) -> Bool {
        print("\(self.name) say \(content)")
        return true
    }
}

Note that with Xcode 8, you can generate the documentation snippet with command+option+/.

 # Lists
 
 You can apply *italic*, **bold**, or `code` inline styles.
 
 ## Unordered Lists
 - Lists are great,
 - but perhaps don't nest
 - Sub-list formatting
 - isn't the best.
 
 ## Ordered Lists
 1. Ordered lists, too
 2. for things that are sorted;
 3. Arabic numerals
 4. are the only kind supported.
