Afroz Khan enhanced the cometchat/docs repository by expanding and clarifying documentation for notification payloads, focusing on integration reliability and developer efficiency. He introduced detailed guidance on the messageObject field within email and SMS payload examples, and added options for including message, sender, receiver, and metadata in notification payloads. Using Markdown and leveraging strong documentation skills, Afroz reorganized the preferences section to improve clarity and streamline the integration process for developers. His work, delivered through semantic and traceable commits, addressed the need for more comprehensive and accessible documentation, though the scope was limited to a single feature over a one-month period.
