 3. The **Parser** uses additional plugins such as the OpenAPI, RAML, or Avro schemas to validate custom schemas of message payloads defined in the **AsyncAPI Document**.
 4. If the **Parser** determines that the original **AsyncAPI Document** is valid, it manipulates the document and returns a set of helper functions and properties and bundles them together into an **asyncapi** variable that is an instance of [**AsyncAPIDocument**](https://github.com/asyncapi/parser-api/blob/master/docs/api.md#asyncapidocument). The **asyncapi** helper functions make it easier to access the contents of the AsyncAPI Document.
 5. At this point, the **Generator** passes the **[asyncapi](generator/asyncapi-document#method-2-asyncapi-and-template)**, the **[originalAsyncAPI](generator/asyncapi-document#method-1-originalasyncapi-and-template)**, and the **params** which collectively make up the **[Template Context](generator/template-context)** to the **Render Engine**.

 7. Once the **Render Engine** receives the **Template Files** and the **Template Context**, it injects all the dynamic values in your react or nunjucks based **Template Files** using the **Template Context**. As a result, the **Render Engine** generates **markdown**, **pdf**, **boilerplate code**, and **anything else** you specified to be generated as output.
 
 > You can generate anything you want using the generator as long as it can be defined in a **Template**.
