## Guides

- [Home](index.md): RevueSDK adds peer-to-peer voice, video and screen sharing to your app. These guides explain the concepts and walk you through each feature.
- [Quickstart](getting-started/quickstart.md)
- [Using RevueSDK with AI](getting-started/ai-tools.md): Give your AI coding assistant the RevueSDK documentation so it writes code against the real API.
- [Initialization and configuration](connecting/initialization.md): `Revue.shared` is the entry point of the SDK. Before you can add friends, invite them or publish tracks, start the SDK with `initialize(_:)`. When you are do…
- [Connection](connecting/connection.md): RevueSDK has no server to connect to. Devices find each other on a peer-to-peer network, and a call starts when a friend accepts your invitation. Getting the…
- [Disconnection](connecting/disconnection.md): A call with one participant ends when either side hangs up or the connection to them fails. Both sides then receive `participantDidDisconnect`. The room itse…
- [Connection state](connecting/connection-state.md): Three different states answer three different questions:
- [Room](core/room.md): `Room` holds everyone you are in a call with: you, and every friend you are connected to. Get the room from `Room.shared`; you cannot create a `Room` yoursel…
- [Events](core/events.md): RevueSDK reports what happens through three delegate protocols. Each one has an empty default for every method, so implement only the events you need.
- [Errors](core/errors.md): Methods that publish tracks or change a published track throw `RoomError`. These are the cases they throw:
- [Logging and debugging](core/logging.md): The SDK reports what it is doing through log entries. You decide where they go: print them, write them to a file, or attach them to a bug report.
- [Participant](participants/participant.md): `Participant` holds what the local and the remote participants have in common. You never create one: the local user is `Room.localParticipant`, and everyone…
- [LocalParticipant](participants/local-participant.md): `LocalParticipant` is the participant that represents this device in a `Room`. Get it from `Room.localParticipant` on `Room.shared`. You use it to publish yo…
- [RemoteParticipant](participants/remote-participant.md): A `RemoteParticipant` is a friend who is in the call with you. Get one from `Room.remoteParticipants` on `Room.shared`, keyed by friend ID.
- [Publishing tracks](participants/publishing.md): Publishing sends one of your tracks to one connected participant. There is no server in between, so every publish names its recipient with `to:`, and only th…
- [Tracks](tracks/tracks.md): A `Track` is one stream of audio or video. Your camera, microphone and screen share are local tracks (`LocalVideoTrack` and `LocalAudioTrack`), and what a re…
- [Track publications](tracks/publications.md): A `TrackPublication` is one participant's copy of a track. When you publish a track to a participant, you get a `LocalTrackPublication` for that participant,…
- [Statistics](tracks/statistics.md): `Track.statistics` holds the latest `TrackStatistics` of a track: what the camera or microphone captures, what is sent or received, and how the connection to…
- [Camera and capture options](media/capture-options.md): A capturer produces the frames or audio of a local track. Each local track has one, in `LocalVideoTrack.capturer` or `LocalAudioTrack.capturer`:
- [Publish options and encoding](media/encoding.md): When you publish a track you can pass options that decide how it is encoded for that participant: the codec, the bitrate and the frame rate. Every publish go…
- [Rendering video](media/rendering-video.md): `VideoView` shows a video track on screen: your own camera, a participant's video, a screen share or a track you fill with your own frames. It is a `UIView`,…
