There are multiple ways in which you can customize the docs generated by Yamldocs. For simple layout / template customizations, such as adding an image or block of default text, you can create custom templates to overwrite the default ones used by Yamldocs. This is also useful to generate content for Hugo websites and other static site generators based on markdown.
If you need a more fine-grained customization, you can create a custom builder to interact directly with your YAML content. This requires some familiarity with PHP development, since you’ll need to create a class that implements a builder interface.
