-## A delivery process you can pick up again
+## Describe the outcome. Start the workflow.
 
-codex-sdlc combines **seven Codex skills** with a **repository-local CLI**. It coordinates requirements, implementation, integration, independent quality control, and optional AI Product Owner review. Tasks, evidence, and decisions stay in your repository so the next session can continue from recorded state.
+Once your project is set up, give Codex a feature request in plain language. **codex-sdlc leads the delivery process** through requirements, planning, implementation, integration, independent quality control, and a final delivery report. It brings you in for clarifications and material decisions; final acceptance remains yours.

+**Amber / YOU:** provide the request and make decisions. **Teal / AI:** coordinate and carry out the delivery work.

+PM coordinates the stages and reviews each handoff. Frontend work follows the reviewed API contract; independent QC follows integration. The optional AI Product Owner offers advice before PM prepares the final package. **Only you accept delivery.**

+### A workflow you can resume
+
+Seven Codex skills and a repository-local CLI keep tasks, evidence, blockers, and decisions in your repository. The next session can continue from recorded state.

 ## Get started
 
 You need **Codex**, **Node.js `>=24.16.0 <25`**, **npm 11**, and an existing application repository. Setup configures your application directories; it does not scaffold application code.
