Turn an incomplete or confusing repository README into a clear setup and usage guide.

I will organize the project overview, prerequisites, installation steps, environment-variable placeholders, run commands, basic usage, testing instructions, and troubleshooting notes using information that can be verified from the repository. The result is designed for developers or reviewers who need to understand and run the project quickly.

This service covers one repository and one README. It does not include writing undocumented product claims, reverse-engineering a broken application, full API reference generation, or exposing real secrets.
