# Overview

Audio, video and screen sharing for your application.

Build rooms with audio, video, screen sharing and messages. Start with the [quickstart](/quickstart).

## Choose your starting point

[REST API](/reference/api/v1/overview) · [React SDK](/reference/sdk/client/react/overview) · [Node SDK](/reference/sdk/server/node/overview)

## Your first room

Your server creates a room and issues a participant token. The browser uses that token to connect, publish media and receive other participants.

1. Create a secret API key in your project environment.
2. Create a room with the REST API or Node SDK.
3. Issue a token for each participant.
4. Join from React and enable camera or microphone access.

Start with the [quickstart](/quickstart). It connects the server and browser in one flow.
