+vLLM-Omni provides a full-duplex runtime for models that can
 continue receiving speech while producing speech. It adds persistent session
 state, model-specific turn policy, overlap handling, playback acknowledgement,
 and optional session resume.
 
 Full duplex is distinct from the turn-based [Realtime Audio API](realtime_api.md).
 
+This page is the endpoint overview. For the complete wire contract, the
+`vllm_omni.clients.duplex.DuplexClient` Python library, and the per-model
+capability gates, see the [Realtime Duplex API guide](realtime_duplex_api.md).
