# Contributing

Issues and merge requests are welcome at
https://gitlab.com/extant2000/one-pane.

## Ground rules

- **A test that cannot fail proves nothing.** If you fix a bug, add a test
  that fails without your fix, and check that it does fail before you submit.
- Measure, do not assume. Two modules with the same line count can be
  different programs.
- Keep dependencies minimal. Every new dependency needs a reason.
- Explain why in comments, not what.

## Before you open a merge request

Run both of these and make sure they pass:

```
npm run build
npm test
```
