-## `DefaultBehaviors` (in LUME)
-
-[LUME](https://lume.io) (a 3D HTML toolkit) uses Element Behaviors, and provides an
-additional
-[`DefaultBehaviors`](https://github.com/lume/lume/blob/v0.3.0-alpha.14/src/behaviors/DefaultBehaviors.ts)
-mixin class that gives Custom Element classes the ability to define which
-behaviors they ship with by
-default, which is super handy!
-
-> **Note** Thinking to move DefaultBehaviors to here instead of `lume`.
-
-To use it first install `lume`:
-
-```sh
-npm install lume
-```
-
-To define a Custom Element with default behaviors, it is done similarly to with `observedAttributes`:
-
-```js
-import {DefaultBehaviors} from 'lume/dist/behaviors/DefaultBehaviors.js'
-
-class SomeElement extends DefaultBehaviors(HTMLElement) {
-	// Define observed attributes
-	static get observedAttributes() {
-		return ['some-attribute', 'other-attribute']
-	}
-
-	// Define default behaviors that the element will have
-	static get defaultBehaviors() {
-		return ['some-behavior', 'click-logger']
-	}
-}
-```
-
-Additionally, the `static defaultBehaviors` property can return an object whose
-key names are behavior names, and whose values are functions that return `true` or
-`false` to determine if a default behavior should be initially added to an
-element or not. The function will receive the element, as well as intial
-behaviors that the element already has defined by the `has=""` attribute when
-the element is created.
-
-For example, suppose we have the following HTML:
-
-<!-- prettier-ignore -->
-```html
-<my-el has="another-behavior"></my-el>
-<my-el has="some-behavior"></my-el>
-```
-
-We define a Custom Element like:
-
-```js
-class MyEl extends DefaultBehaviors(HTMLElement) {
-	static get defaultBehaviors() {
-		return {
-			'click-logger': (element, initialBehaviors) => {
-				// For sake of example, suppose that if the element has
-				// `another-behavior`, then we do not want it to have the `click-logger`
-				// behavior:
-				if (initialBehaviors.includes('another-behavior')) {
-					return false
-				}
-				return true
-			},
-		}
-	}
-}
-
-customElements.define('my-el', MyEl)
-```
-
-When the `my-el` elements are created, only the one without the `another-behavior` will have
-`click-logger` added to it, so the resulting DOM will be as follows:
-
-<!-- prettier-ignore -->
-```html
-<my-el has="another-behavior"></my-el>
-<my-el has="some-behavior click-logger"></my-el>
-```
