+Our $1,000,000 Kickstarter stretch goal brought our **SVG Framework** to all of
+Font Awesome 5. We are super-excited to bring this to you.
+
+As a Pro backer your early access preview gives you access to this new
+framework and we need your help!
+
+[We're collecting feedback here.](https://github.com/FortAwesome/Font-Awesome-Pro/issues/412)
+
+### SVG Framework using the JavaScript implementation
+
+Pros:
+
+- Most familiar (still use `<i class="fa fa-user"></i>`)
+- Replaces icons with inline `<svg>` elements for you
+- Includes and packages the CSS features of Font Awesome (like `.fa-spin`)
+- Easy, automatic accessibility handling
+- Support for unicode and ligatures (not complete yet)
+
+Cons:
+
+- You need JavaScript
+- Not as performant as sprites
+- DOM mutations take special handling
+- Has a few moving parts
+
+Browser support (tested using BrowserStack):
+
