This PR is a documentation only one which: - addresses the #7231 by adding a paragraph in `docs/getting-started.md` in the tips category to encourage users to load everything needed in their environment - corrects link referencing in `docs/platform-sandboxing.md` so that the page link opens at the right section - removes the explicit heading IDs like {#my-id} in `docs/advanced.md` which are not supported by GitHub and are **not** rendered in the UI: <img width="1198" height="849" alt="Screenshot 2025-11-26 at 16 25 31" src="https://github.com/user-attachments/assets/308d33c3-81d3-4785-a6c1-e9377e6d3ea6" /> This caused the following links in `README.md` to not work in `main` but to work in this branch (you can test by going to https://github.com/openai/codex/blob/docs/getting-started-enhancement/README.md) - the MCP link goes straight to the correct section now: ```markdown - [**Advanced**](./docs/advanced.md) - [Tracing / verbose logging](./docs/advanced.md#tracing--verbose-logging) - [Model Context Protocol (MCP)](./docs/advanced.md#model-context-protocol-mcp) ``` --------- Signed-off-by: lionel-oai <lionel@openai.com> Signed-off-by: lionelchg <lionel.cheng@hotmail.fr> Co-authored-by: lionelchg <lionel.cheng@hotmail.fr>
npm i -g @openai/codex

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex
Quickstart
Installing and running Codex CLI
Install globally with your preferred package manager. If you use npm:
npm install -g @openai/codex
Alternatively, if you use Homebrew:
brew install --cask codex
Then simply run codex to get started:
codex
If you're running into upgrade issues with Homebrew, see the FAQ entry on brew upgrade codex.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
