## Docs

- [Home](https://docs.dtelecom.org/index.md): Platform overview, features, and quick React example
- [Getting Started](https://docs.dtelecom.org/guides/getting-started.md): Step-by-step guide to build a working video call — API keys, env vars, SDK install, server token + getWsUrl()/getApiUrl(), client connection
- [Architecture](https://docs.dtelecom.org/guides/architecture.md): How dTelecom differs from LiveKit — decentralized SFU nodes, Solana registry, Ed25519 signing, connection flow diagram
- [Access Tokens](https://docs.dtelecom.org/guides/access-tokens.md): Creating JWT tokens with Ed25519 signing, room permissions (canPublishData), token expiration, participant metadata, role-based metadata pattern
- [Server APIs](https://docs.dtelecom.org/guides/server-api.md): RoomServiceClient API (initialized via getApiUrl()) — CreateRoom, ListRooms, DeleteRoom, ListParticipants, GetParticipant, UpdateParticipant, RemoveParticipant, UpdateRoomMetadata, MutePublishedTrack, UpdateSubscriptions, SendData, host controls pattern (kick/mute authorized from the caller's verified access token). Note: write ops broadcast via P2P (work from any node), read ops are local to one node's in-memory store.
