+## Performance
+
+I wrote this from the ground up partly because I needed an autocomplete with better performance than others I'd tried. I've optimised the JavaScript where I can, but it's the actual list _rendering_ that's a hit to performance. In my testing, modern browsers can render huge lists (1000+ items) just fine (on my laptop, averaging 40ms in Chrome, and under 20ms in Firefox).
+
+As we all know however, Internet Explorer _sucks_. If you need to support IE11 (or earlier), I suggest either setting the `maxResults` option to 200 or less, or using a sensible combination for the `delay` and `minLength` options. Testing on my laptop, the list rendering in IE11 would take on average: 55ms for 250 items, 300ms for 650 items, and over 600ms for 1000 items.

-At its core, the autocomplete requires only an element, and a source. When the element is an input, its value will be set using the user's selection(s). If a source isn't provided however, and the element is either a `<select>`, or is an element with child checkboxes, those will be used to build up the source.
+At its core, the autocomplete requires only an element, and a `source`. When the element is an input, its value will be set using the user's selection(s). If a `source` option isn't provided however (is falsy, or an empty Array), and the element is either a `<select>`, or has child checkboxes, those will be used to build up the `source`.
