README that people actually readTemplateLow risk

Write a README for {{project_name}}: {{project_description}}.

Order:
1. One-line description and who it's for.
2. Screenshot or demo placeholder.
3. Quick start (copy-paste commands, under 5 steps).
4. Configuration (table: name, required, default, description).
5. Common tasks / usage examples.
6. How it works (short, optional diagram).
7. Contributing and license.

Use short sections and code blocks. Assume the reader has 2 minutes.
