CodexGuide

CodexGuide is a community-maintained handbook for learning how to use OpenAI's Codex tools effectively. Codex has grown from a simple code-writing assistant into a broader system that spans desktop apps, command-line tools, cloud services, browser extensions, and IDE integrations. This project helps people navigate that ecosystem with practical, task-oriented guidance rather than just a list of commands.

The guide is organized into several learning paths. Beginners can follow a step-by-step route covering installation, account setup, and completing a first task. Developers looking to integrate Codex into real projects can learn about the command-line interface, project-level rule files called AGENTS.md, and sandbox/security boundaries. There are also advanced tutorials for team practices, automation, and troubleshooting. The content is primarily written in Chinese but aims to serve a global audience across both technical and non-technical roles.

The audience spans a wide range. A first-time user might follow the beginner path to get the desktop app running and complete a simple task. A developer could use it to learn how Codex modifies code in a real repository, including how to set safety boundaries around file access and command execution. Content creators, researchers, and product managers can find examples of using Codex for writing, presentations, research, and knowledge management. Team leads get guidance on building reusable templates, permission structures, and review processes. The guide also includes a comparison of different Codex entry points — desktop, CLI, cloud, IDE, and mobile — to help people choose the right one for their situation.

The project emphasizes official sources, prioritizing OpenAI's own documentation for facts about features, pricing, and security. Key pages are tagged with a "last verified" date so readers know when to double-check against official updates. The full documentation is available as an online site with navigation, search, and screenshots, though the GitHub repository contains the same structured content organized into guide, quick-start, advanced, recipes, and reference sections. It is an independent community effort, not an OpenAI product.
