# HorizontalRule
Use this extension to render a `<hr>` HTML tag. If you pass `<hr>` in the editor’s initial content, it’ll be rendered accordingly.

Type three dashes (`---`) or three underscores and a space (`___ ​`) at the beginning of a new line and it will magically transform to a horizontal rule.
