## Quickstart
### Installing and running Codex CLI
Install globally with your preferred package manager. If you use npm:
```shell
npm install -g @openai/codex
```
Alternatively, if you use Homebrew:
```shell
brew install codex
```
Then simply run `codex` to get started:
```shell
codex
```
<details>
<summary>You can also go to the <a href="https://github.com/openai/codex/releases/latest">latest GitHub Release</a> and download the appropriate binary for your platform.</summary>
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`
- Linux
- x86_64: `codex-x86_64-unknown-linux-musl.tar.gz`
- arm64: `codex-aarch64-unknown-linux-musl.tar.gz`
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.

### Using Codex with your ChatGPT plan

</p>
Run `codex` and select **Sign in with ChatGPT**. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Team, Edu, or Enterprise plan. [Learn more about what's included in your ChatGPT plan](https://help.openai.com/en/articles/11369540-codex-in-chatgpt).
You can also use Codex with an API key, but this requires [additional setup](./docs/authentication.md#usage-based-billing-alternative-use-an-openai-api-key). If you previously used an API key for usage-based billing, see the [migration steps](./docs/authentication.md#migrating-from-usage-based-billing-api-key). If you're having trouble with login, please comment on [this issue](https://github.com/openai/codex/issues/1243).
### Model Context Protocol (MCP)
Codex CLI supports [MCP servers](./docs/advanced.md#model-context-protocol-mcp). Enable by adding an `mcp_servers` section to your `~/.codex/config.toml`.
### Configuration
Codex CLI supports a rich set of configuration options, with preferences stored in `~/.codex/config.toml`. For full configuration options, see [Configuration](./docs/config.md).
