> **Maestro’s take:** Skip the first eight minutes if you already have Codex installed. Do not skip the repository-guidance section. Agents become much less “mysterious” once you stop making them rediscover your rules.

## Watch

## TL;DR

OpenAI’s official walkthrough moves from installing the CLI and editor extension through repository setup, `AGENTS.md`, prompting patterns, MCP configuration, headless mode and the SDK.

It is a useful single reference for developers who have tried one ad-hoc session and now want a repeatable workflow.

## Maestro’s chapter guide

- **Start:** installation and first run.
- **Stay for:** repository guidance and prompting patterns.
- **Return later for:** MCP, headless workflows and the SDK.
- **Do after watching:** write ten lines of repository-specific guidance before asking for another feature.
