Josselin Mariette enhanced the SEKOIA-IO/documentation repository by updating the FAQ section to clarify rate-limiting and error handling policies. Focusing on Markdown-based documentation, Josselin defined precise thresholds for request rates, response times, and error scenarios, and detailed the duration of impact for blocked requests. This targeted update aimed to improve developer onboarding and reduce support queries by making API usage and reliability policies more transparent. The work demonstrated a strong grasp of technical writing and documentation best practices, delivering a focused feature that addressed a specific need without introducing code changes or bug fixes during the one-month contribution period.
