Developed comprehensive documentation for the SignalWire Realtime SDK within the signalwire/docs repository, focusing on namespaces such as Voice, Video, Chat, Messaging, PubSub, and Task. The work involved creating detailed API references, including class, method, property, and event documentation, as well as practical usage examples and type definitions to support developer onboarding and effective SDK adoption. Leveraging Markdown and expertise in API reference design, the documentation established a clear baseline for future updates and aimed to reduce support overhead. This effort provided a structured foundation for consistent SDK documentation, enhancing clarity and usability for developers integrating SignalWire’s realtime features.
