 The FAIR principles have become a global standard for data management and reproducibility. However, there is still a gap between the ideal and reality when it comes to implementing these principles. To bridge this gap, the FAIR Cookbook was created as an open, online resource of practical recipes for data managers in the life sciences. This Cookbook provides step-by-step instructions on how to make data more findable, accessible, interoperable, and reusable, FAIR. It also outlines the necessary skills, tools, and technologies needed to reach higher levels of fairness. Additionally, the Cookbook serves as a guide for data managers to assess their current level of fairness and identify areas where improvements can be made.
