# Repository instructions

- Keep Chromium headed by default. Do not add `--headless` to `docker-entrypoint.sh`.
- Keep upstream downloads restricted to `adryfish/fingerprint-chromium` Linux x86_64 release assets.
- Keep registry credentials in workflow secrets; never commit credentials.
- Before submitting changes, run `./tests/check.sh`, build the image, and smoke-test Chromium.
