# Contributing

Thank you for improving Cody's Line Counter.

## Set up

Requirements:

- Node.js 20 or newer
- npm 10 or newer

```sh
git clone https://github.com/CodyKoInABox/codys-linecounter.git
cd codys-linecounter
npm install
npm run validate
```

## Making changes

Keep the scanner dependency-light and deterministic. New language definitions
belong in `src/languages.js`; add focused cases for both detection and line
classification. Bug fixes should include a regression test.

Before opening a pull request, run:

```sh
npm run validate
npm run test:coverage
npm pack --dry-run
```

Please keep commits focused and explain any category-semantics or public API
changes in the pull request. User-visible changes should be added to
`CHANGELOG.md`.
