+## Animate Scrolling
+
+You can animate a scroll to a position or an element easily using `Transition.scroll`.
+
+### Scroll To a Position
+
+You can scroll to a Y position like so:
+
+```js
+Transition.scroll(0, 500); // Transition.scroll(y, duration)
+```
+
+### Scroll to an Element
+
+You can scroll to the top of an element like so:
+
+```js
+Transition.scroll(element, 500); // Transition.scroll(element, duration)
+```
+
+#### Scroll to the bottom of an element
+
+You can scroll to the bottom of an element like so:
+
+```js
+Transition.scroll(element, 500, { align: 'bottom' });

+### Scroll Duration
+
+(`Transition.scroll` only.) If you don't want scrolling short distances to take as long as scrolling long distances (or vice versa), you can specify the duration per every 100 pixels scrolled, like so:
+
+```js
+Transition.scroll(0, { per100: 30 }); // Speed is 30 milliseconds per 100 pixels scrolled
+```
+
+### Scroll Element
+
+(`Transition.scroll` only.) If you want to scroll inside of an element (e.g. a wrapper element, with overflow: scroll), you can specify that, like so:
+
+```js
+Transition.scroll(0, 500, { element: wrapper }); // Instead of scrolling in the window, scroll in `wrapper`
