Mathews Mathai updated the notification preferences documentation in the cometchat/docs repository, focusing on clarifying user guidance and aligning the SMS and email notification API documentation with current implementation. He used Markdown and YAML to refactor the API specification, ensuring that the documentation accurately reflected the system’s behavior. His work included correcting ambiguous descriptions and providing a single, authoritative source for notification settings, which helps reduce support friction and streamlines developer onboarding. Although the scope was limited to documentation, the changes improved accuracy and traceability, with three well-documented commits that enhanced both user-facing and developer-facing materials.
