 ### Addon usage
 
+#### Adding Custom Plugins
+
+You can add custom plugins to be used during transpilation of the `addon/` or `addon-test-support/`
+trees by ensuring that your addon's `options.babel` is properly populated (as mentioned above in the
+`Options` section).
+
+For example, to add `babel-plugin-transform-object-rest-spread` so that your addon can use object
+rest/spread you would do something like this:
+
+```js
+module.exports = {
+  name: 'my-special-addon',
+
+  init() {
+    this._super && this._super.init.apply(this, arguments);
+
+    this.options = this.options || {};
+    this.options.babel = this.options.babel || {};
+    this.options.babel.plugins = this.options.babel.plugins || [];
+    this.options.babel.plugins.push('transform-object-rest-spread');
+  };
+}
+```
+
+#### Additional Trees
+
 For addons which want additional customizations, they are able to interact with
 this addon directly.
