Watch: Getting started with Codex, from install to MCP
2026-01-12
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.

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.
