Docs Feedback is a new feature that allows users to provide feedback on documentation through simple upvote and downvote mechanics, enabling businesses to identify areas of improvement and boost customer success. By integrating this feature with analytics tools like Posthog, companies can gain valuable insights into user behavior and make data-driven decisions to enhance their documentation. The feature can be easily enabled by adding a configuration option to the mint.json file, allowing users to customize the experience and collect feedback on their documentation.
