All of the basic Markdown formatting is supported (powered by kramdown).

Additionally, Markdown is extended to support the following:

#### Math

$f(n) = \begin{cases} \frac{n}{2}, & \text{if } n \text{ is even} \\ 3n+1, & \text{if } n \text{ is odd} \end{cases}$The code for the example above is:

```
$$
f(n) = \begin{cases}
\frac{n}{2}, & \text{if } n \text{ is even} \\
3n+1, & \text{if } n \text{ is odd}
\end{cases}
$$
```

Both inline and display modes are supported. Math is rendered server-side and does **not** require JavaScript. Powered by KaTeX.

#### Syntax highlighting

Specify the language of a code block and the syntax will be highlighted:

1puts "Hello, #{user}" 2add_5 = -> x { x + 5 } 3 4class Greeter 5 # ... 6end
