Adobe Fonts for website, can't find a code!

Hello, 

I am trying to use this font > https://fonts.adobe.com/fonts/neue-haas-grotesk on our website. 

I can't find a way to add this font, 

I can only see instructions on how to use the it... but I can't find a way to add a project or load the font. 

Thanks 

Firas.
