Ensure configuration documentation clearly and accurately describes environment variables, command-line flags, and their relationships. Pay special attention to precedence rules, equivalent options, and proper grammar when explaining configuration behavior. Key areas to review: - Verify environment variable names and their effects are correctly documented - Clearly explain relationships between environment variables and command-line flags - Document precedence rules (e.g., command-line flags override environment variables) - Use consistent and grammatically correct language when describing configuration options Example of good documentation: ```yaml # Clear precedence explanation Setting the `COMPOSE_PROJECT_NAME` environment variable is equivalent to the `-p` flag, and `COMPOSE_PROFILES` environment variable is equivalent to the `--profiles` flag. If a flag is set via the command line, the associated environment variable is ignored. ``` This ensures developers understand exactly how different configuration methods interact and which takes precedence in various scenarios.
