Enhanced dbt Documentation with Doc Blocks
An intuitive method for creating reusable and dynamic dbt documentation.
In an era where data is the driving force behind decision-making, the tools we use to handle, transform, and make sense of that data are pivotal. Among these, dbt (Data Build Tool) Cloud has emerged as a game-changer, offering analysts a platform to manage complex SQL transformations, tests, and documentation in their data warehouses. The true power of dbt, however, goes beyond just data transformation — it also resides in its robust documentation capabilities, specifically through a feature called ‘doc blocks’.
Doc blocks in dbt provide an intuitive method for creating reusable and dynamic content, thereby promoting more efficient, comprehensive, and maintainable documentation. But to leverage doc blocks to their full potential, one must understand how to create, reference, and manage them effectively.
In this guide, I will take you through the journey of understanding and maximizing the use of doc blocks in dbt Cloud. We will start with the basics — exploring what doc blocks are and why they are important, then delve deeper into how to create and use them effectively, and finally, we will explore some techniques and best practices for doc block use in your dbt projects.
Whether you are a beginner just starting out with dbt, or an experienced user looking to enhance your documentation practices, this guide will provide valuable insights to elevate your dbt Cloud experience.

What are Doc Blocks?
Doc blocks are reusable chunks of markdown that can be written once and referenced from multiple places in your dbt project. These blocks are often used to write more extensive documentation for models, sources, tests, and other dbt objects.
With doc blocks, you can construct comprehensive documentation about the structure, behavior, and usage of your dbt data models, contributing to better understanding and smoother collaboration amongst team members.
