 Slate's goal is to support all the modern browsers on both desktop and mobile devices.
 
-However, right now Slate is in beta, so its support is not as full as it will later be. It's currently tested against the latest few versions of Chrome, Firefox and Safari on desktops. It isn't currently tested against Internet Explorer or Edge, or against mobile devices. If you want to add more browser or device support, we'd love for you to submit a pull request!
