 # API Reference
 
-We use Pydoc-Markdown to create Markdown files from the docstrings in our code. There is a Github Action that regenerates the API pages when tags are pushed or when manually triggered.
+We use [haystack-pydoc-tools](https://github.com/deepset-ai/haystack-pydoc-tools) to create Markdown files from the docstrings in our code. There is a [Github workflow](https://github.com/deepset-ai/haystack-experimental/blob/main/.github/workflows/docusaurus_sync.yml) that regenerates the API reference at release time.
 
-If you want to generate a new Markdown file for a new Haystack module, create a `.yml` file in `pydoc` which configures how Pydoc-Markdown will generate the page and commit it to main.

+All the updates to API reference get pushed to documentation when a new version is released.
 
 ### Configuration
 
-Pydoc will read the configuration from a `.yml` file which is located under `pydoc`. Our files contain three main sections:
-
-- **loaders**: A list of plugins that load API objects from python source files.
-    - **type**: Loader for python source files (we use `haystack_pydoc_tools.loaders.CustomPythonLoader`)
-    - **search_path**: Location of source files (relative to the config file)
-    - **modules**: Modules which are used for generating the markdown file
-    - **ignore_when_discovered**: Define which files should be ignored
-- **processors**: A list of plugins that process API objects to modify their docstrings (e.g. to adapt them from a documentation format to Markdown or to remove items that should not be rendered into the documentation).
-    - **type: filter**: Filter for specific modules
-    - **documented_only**: Only documented API objects
-    - **do_not_filter_modules**: Do not filter module objects
-    - **skip_empty_modules**: Skip modules without content
-    - **type: smart**: Smart processor for docstring processing
-    - **type: crossref**: Cross-reference processor
-- **renderer**: A plugin that produces the output files. We use a custom DocusaurusRenderer based on the Markdown renderer. It makes sure the Markdown files comply with Docusaurus requirements.
-    - **type**: Define the renderer which you want to use. We are using the DocusaurusRenderer to make sure the files display properly in Docusaurus.
-    - **description**: Add a short description of the page. It shows up right below the page title.
-    - **id**: This is the Docusaurus page ID to make sure the doc lands in the right section of Haystack docs.
-    - **title**: The title of the doc as it will appear on the website. Make sure you always add "API" at the end.
-    - **markdown**:
-        - **descriptive_class_title**: Remove the word "Object" from class titles.
-        - **descriptive_module_title**: Adding the word "Module" before the module name.
-        - **add_method_class_prefix**: Add the class name as a prefix to method names.
-        - **add_member_class_prefix**: Add the class name as a prefix to member names.
-        - **filename**: File name of the generated file, use underscores to separate each word.
+For configuration details, see the [haystack-pydoc-tools documentation](https://github.com/deepset-ai/haystack-pydoc-tools/blob/main/README.md#configuration) or inspect the existing `.yml` files in `pydoc`.
