## Переваги стандартів, альтернативна документація { #standards-based-benefits-alternative-documentation }

І оскільки згенерована схема відповідає стандарту [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md), існує багато сумісних інструментів.

    Generate and return the HTML response that loads ReDoc for the alternative

    You would only call this function yourself if you needed to override some parts,
    for example the URLs to use to load ReDoc's JavaScript and CSS.
