  "account": "Before opening a pull request with new code, it is crucial to ensure the associated documentation remains accurate and up-to-date. To streamline this process, follow a three-step check that can be completed in just five minutes, saving review cycles and preventing documentation discrepancies.\n\nFirstly, always verify the functionality of every code example within the README files and documentation folders. As function signatures and configuration options evolve, code snippets can quickly become outdated. To maintain accuracy, copy each command or snippet verbatim into a clean terminal or test script. Confirm that the code executes without errors, ensuring the documentation reflects the most recent implementation.\n\nSecondly, scrutinize any changes to environment variables and configuration flags. If your pull request introduces, renames, or deprecates an environment variable or setting, carefully review the configuration table. Ensure the default value is listed, clarify whether the variable is mandatory, and describe the behavior when the variable is omitted. This step guarantees that users understand the implications of the configuration changes and reduces the likelihood of misunderstandings.\n\nLastly, examine the troubleshooting steps for common failure modes. When introducing new setup steps or dependencies, document the error message that appears if a step is skipped. Providing two lines showcasing the expected failure message and the direct fix assists teammates in resolving onboarding issues independently, without the need for chat inquiries. By addressing potential pitfalls proactively, the documentation becomes more robust and easier to navigate. Following these three checks before submitting a pull request not only saves time but also ensures the documentation remains consistent with the latest codebase, leading to a smoother review process.",
