+# Codex CLI
+
+**Lightweight coding agent that runs in your terminal**
+
+Codex CLI is OpenAI's terminal-based coding agent with built-in support for the Agent Client Protocol.
+
+## Features
+
+- **Agent Client Protocol (ACP)**: Native ACP support for seamless editor integration
+- **Zed Integration**: Built-in support in Zed IDE (v0.208+)
+- **Terminal-First**: Designed for developers who live in the command line
+
+## ACP Integration
+
+Codex works out-of-the-box with ACP-compatible editors:
+- Zed: Open agent panel (cmd-?/ctrl-?) and start a new Codex thread
+- Other ACP clients: Use the `codex-acp` command
+
+## Installation
+
+Install globally via npm or Homebrew:
+- npm: `npm i -g @openai/codex`
+- Homebrew: `brew install --cask codex`
+
+For ACP adapter (used by editors): Install from https://github.com/zed-industries/codex-acp/releases
