 There is a list of [community maintained templates](https://www.asyncapi.com/docs/tools/generator/template#generator-templates-list), but what if you do not find what you need? In that case, you'll create a user-defined template that generates custom output from the generator.
 Before you create the template, you'll need to have an [AsyncAPI document](https://www.asyncapi.com/docs/tools/generator/asyncapi-document) that defines the properties you want to use in your template to test against. In this tutorial, you'll use the following template saved in the **test/fixtures/asyncapi.yml** file in your template project directory.
