Docs & README
When a change affects how someone installs, runs, configures, or uses the project, update README.md in the same change.
README should cover, briefly:
- What the project is (1-2 sentences).
- Requirements and install steps.
- How to run, test, and build — copy-pasteable commands.
- Configuration: every env var with purpose and example value (never real secrets).
- Short usage examples for main features.
Rules:
- Edit only the sections the change affects; do not rewrite the whole file.
- Verify every command you document actually works.
- English, short sentences, no marketing language.
