 Hooks are functions called by the generator on a specific moment in the generation process. Hooks can be anonymous functions but you can also add function names. These hooks can have arguments provided to them or being expected to return a value.

Name is required only if you keep hooks in non default location or in a separate library, because such hooks need to be explicitly configured in the configuration file.

+## Official library
+
+It is a library of reusable hooks that you can use in your templates. You only have to add its name to the configuration: `@asyncapi/generator-hooks` and specify which hook you want to enable.
+
+This library consists of the following hooks:
+|Hook name|Hook type|Description|
+|---|---|---|
+| `createAsyncapiFile` | `generate:after` | It creates an AsyncAPI file with the content of the spec file passed to the generator. By default, it creates the file in the root of the generation output directory. This hook also supports custom parameters that the user can pass to template generation. The parameter called `asyncapiFileDir` allows the user to specify the location where the spec file should be created. To make your template users use this parameter, you need to add it to the configuration of your template like other parameters |
+
+1. In your template configuration in `package.json` specify you want to use this library and what hook exactly:
+    ```json
+    {
+      "generator": {
+          "hooks": {
+              "@asyncapi/generator-hooks": "createAsyncapiFile"
+          }
+      }
+    }
+    ```
+1. Some hooks support custom parameters that template's user can use to specify different behaviour of the hook. To enable these, you need to also add them to the list of your template's parameters:
+    ```json
+    {
+      "generator": {
+          "parameters": {
+            "asyncapiFileDir": {
+                "description": "This template by default also outputs the AsyncAPI document that was passed as input. You can specify with this parameter what should be the location of this AsyncAPI document, relative to specified template output."
+            }
+        }
+      }
+    }
