You create two Chat users, Alice and Bob, and use them to: * Send and receive messages * Use Group channel features, such as typing indicators, read receipts, replies, files, and reactions * Invite users to channels, join channels, and leave them These tutorials are for running commands yourself in a terminal. If you use an AI coding agent, such as Claude Code or Codex, describe what you want in plain words instead, and the agent runs the commands. See [Example requests](/readme/ai-agents.md#example-requests). To add Chat to your app's code, see [Add Chat](/plugins/client/add-chat.md). ## Terms used in these tutorials
