 The closing bracket should be on its own line. This allows attributes to be shuffled and edited without having to move the bracket around. It also makes it easier to scan vertically and match opening and closing brackets. This format

+## Accessibility
+
+### Don't use the `title` attribute
+
+The `title` has no clear role within the accessibility standards. 
+[See the HTML5 spec](http://w3c.github.io/html/dom.html#the-title-attribute) for more information.
+
+To provide supplementary, descriptive information about a form control, button, link, or other element, use
+a tooltip component instead.

+### Tooltips
+
+Elements which act as tooltips should have the `role="tooltip"` attribute and an ID to which the
+described element can point to with the `aria-describedby` attribute. For example:
+
+```html
+<div
+  class="kuiTooltip"
+  role="tooltip"
+  id="visualizationsTooltip"
+>
+  Visualizations help you make sense of your data.
+</div>
+
+<button aria-describedby="visualizationsTooltip">
+ Visualizations
+</button>
+```
+
+### Prefer `button` and `a` when making interactive elements keyboard-accessible
+
+If something is meant to be clickable, favor using a `button` or `a` tag before over the `kui-accessible-click` directive or `KuiKeyboardAccessible` component. These tools are useful as they augment non-clickable elements with `onkeypress` and `onkeyup` handlers, allowing non-clickable elements to become keyboard accessible. However, `button` and `a` tags provide this functionality natively.
+
+### Use `tabindex` to make elements tabbable
+
+When added to the tab order, elements become focusable via non-sticky-mode keyboard navigation.
+To add an element to the tab order, you must add an `id` attribute as well as a `tabindex` attribute. If you don't know which number to use for the tab index, or if you simply want to add it to the general flow of the document, use `tabindex="0"`.
