WikiText is a concise, expressive way of typing a wide range of text formatting, hypertext and interactive features. It allows you to focus on writing without a complex user interface getting in the way. It is designed to be familiar for users of Markdown but with more of a focus on linking and the interactive features.

WikiText can also be inserted to the text field using the Editor toolbar buttons.
