# Markdown

final class in quittio/core

`Quittio\Core\View\Markdown` · [Source](https://github.com/Quittio/quittio/blob/v0.7.1/packages/core/src/View/Markdown.php#L17)

Safe Markdown subset for texts: paragraphs, lists, bold and italic. HTML in the input is shown as text, links keep only their text.

Descriptions and notes are also part of the e-invoice XML and are printed as plain text by default (`self::plain()`); Markdown for them is opt-in (option "markdown"), because formatting changes the displayed text compared with the XML (e.g. "\*" for emphasis).

## Methods \#
