Almost the same as we explained in the Webpack user section, we need to retrieve the aurelia-i18n plugin and backend server from the npm repositories:

npm install aurelia-i18n --save
npm install i18next i18next-xhr-backend --save

Now, we need to tell our project that we have new dependencies to be configured. Open your Aurelia configuration file (aurelia.json) and look for the dependencies section. You must add the following entries:

{
    "name": "i18next",
    "path": "../node_modules/i18next/dist/umd",
    "main": "i18next"
  },
  {
    "name": "aurelia-i18n",
    "path": "../node_modules/aurelia-i18n/dist/amd",
    "main": "aurelia-i18n"
  },
  {
    "name": "i18next-xhr-backend",
    "path": "../node_modules/i18next-xhr-backend/dist/umd",
    "main": "i18nextXHRBackend"
  }

Finally, we are done with the plugins. Now, let's configure it to our application!
