## Installing dependencies

```bash
$ yarn install
```

`npm` doesn't install the correct dependencies for `eslint` so we use `yarn`.

## Regenerating dist/index.js

```bash
$ yarn run package
```

It is recommended to add this as a `git` `pre-commit` hook:

```bash
$ cp pre-commit .git/hooks/pre-commit
```

## Adding a new Ruby version

Add the new version in `ruby-builder-versions.json`,
then follow the steps above in [Regenerating dist/index.js](#regenerating-distindexjs) to update `dist/index.js`.
Finally, update the "Supported Versions" section of the README if needed.
