Worked on enhancing the FPM configuration documentation within the php/doc-en repository, focusing on improving clarity and reducing the risk of user misconfiguration. The work involved adding comprehensive details about ondemand process management and ensuring full coverage of PHP-FPM process manager modes. Using XML for documentation and leveraging configuration management expertise, the developer addressed formatting inconsistencies and corrected a missing closing brace in configuration examples. These targeted improvements aligned the documentation with actual software behavior, clarified the relevance of pm.max_children for ondemand mode, and contributed to better maintainability. The updates support faster onboarding and help minimize future support queries.
