How do I use i18n ? (jhipster)
Did you see our documentation at https://jhipster.github.io/development.html ? At the end of the page, there is an explanation on how i18n works with JHipster.
We in fact rely on https://github.com/angular-translate/angular-translate so this where you should go for more documentation (our policy is not to document third-party tools we are using, but we forward you to their documentation instead)
