# i18n-iso-languages
i18n for ISO 639 language codes. We support Alpha-2, Alpha-3 B and T codes from https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes
This packages is heavily based on [i18n-iso-countries](https://github.com/michaelwittig/node-i18n-iso-countries).
We intent to keep the interface of i18n-iso-languages as close as possible to i18n-iso-countries.
## Installing
