# Contributing

Issues and merge requests are welcome at
https://gitlab.com/extant2000/evidence-record.

## Ground rules

- A test that cannot fail proves nothing. If you fix a bug, add a test and
  check that it fails against the unfixed code before you submit.
- Measure, don't assume. Two modules with the same line count can still be
  different programs.
- Keep dependencies minimal. Every new runtime dependency needs a reason.
- Explain why in comments, not what. The what is already in the code.
- A breaking change needs a major version bump and a note in CHANGELOG.md.

## Before you open a merge request

Run both of these and make sure they pass:

    npm run build
    npm test
