+[TypeIt](https://www.typeitjs.com) is the most versatile JavaScript tool for creating typewriter effects on the planet. With a straightforward configuration, it allows you to type single or multiple strings that break lines, delete & replace each other, and it even handles strings that contain complex HTML. 
+
+Blowfish implements a sub-set of TypeIt features using a `shortcode`. Write your text within the `typeit` shortcode and use the following parameters to configure the behavior you want.
