+### Custom assertion module
+
+You can use any assertion module instead or in addition to the one that comes with AVA, but you won't be able to use the `.plan()` method, [yet](https://github.com/sindresorhus/ava/issues/25).
+
+```js
+var assert = require('assert');
+
+test(function (t) {
+	assert(true);
+	t.end();
+});
+```
+
+
+### ES2015 support
+
+You can write your tests in ES2015:
+
+```js
+test(t => {
+	t.ok();
+	t.end();
+});
+```
+
+And run it in any node version.
+
+```sh
+$ ava
+```
+
+Also you can use your local `babel` instead of built-in.
+
+For example, package.json:
+
+```json
+{
+	"devDependencies": {
+		"ava": "^0.1.0",
+		"babel": "^5.8.0"
+	},
+	"scripts": {
+		"test": "ava"
+	}
+}
+```
