 翻訳文字列を含むカスタムファイルを `i18n/[code].yaml` に作成することでデフォルトの翻訳をオーバーライドできます。このメソッドを使って新しい言語を追加することもできます。新しい翻訳をコミュニティと共有したい場合、[Pull Request](https://github.com/jpanther/congo/pulls)を作ってください。

 The default translations can be overridden by creating a custom file in `i18n/[code].yaml` that contains the translation strings. You can also use this method to add new languages. If you'd like to share a new translation with the community, please [open a pull request](https://github.com/jpanther/congo/pulls).
