+`async`/`await` is a clearer pattern to follow than using callbacks.
+
+## Rule details
+
+ES2017's `async`/`await` makes it easier to deal with asynchronous code than the
+callback pattern.
+
+Examples of **incorrect** code for this rule:
+
+```js
+cb()
+callback()
+doSomething(arg, (err) => {})
+function doSomethingElse(cb) {}
+```
+
+Examples of **correct** code for this rule:
+
+```js
+await doSomething(arg)
+async function doSomethingElse() {}
+yield yieldValue(err => {})
+eventEmitter.on('error', err => {})
+```
+
+## When Not To Use It
+
+If you are not targeting an ES2017 or higher environment and cannot transpile
+`async`/`await`, you should disable this rule.
