+- By using options `extraDecorator: ['YourDecorators']` and `extraProperties: ['yourProperties']` you can extend the default list that is used for the checks.
+
+```ts
+import {Component} from '@angular/core';
+
+@YourDecorators({
+ yourProperties: [
+ Apple,
+ Banana,
+ Paprika,
+ SomethingElse,
+ ],
+})
+```
