-Codex CLI is OpenAI's official command-line tool that brings the power of their latest reasoning models directly to your terminal. It's built for developers who already live in the terminal and want ChatGPT-level reasoning plus the power to actually run code, manipulate files, and iterate - all under version control.
+Codex CLI brings OpenAI's reasoning models to the command line. It can create or edit files,
+run commands in a sandbox, and track work under version control. Non-technical curators
+can prompt tasks and review results directly from the terminal.
 
-## Key Features

-- **Multimodal inputs** – Pass text, screenshots, or diagrams and let the agent generate or edit code accordingly
