Worked on citrineos/citrineos-core to enhance runtime configuration practices by improving project documentation. Focused on clarifying how environment variable overrides can be used to adjust configuration values at runtime, the work included updating the README with detailed instructions and a practical example for overriding the AMQP URL. This documentation, written in Markdown, aimed to streamline onboarding and reduce configuration errors for users deploying the system. No bug fixes were recorded during this period, as the primary emphasis was on documentation quality and user guidance. The contribution leveraged strong documentation skills to align deployment processes with best practices for configuration management.
