In the previous chapter, we got our bearings as we learned about Drupal internationalization at a conceptual level. Now we will get down to business and begin our localization process.

This chapter starts with setting up a test site to use for the book exercises. Once the site is ready, we'll add several new languages and configure language detection so that we can view each language using different URLs. With the detection in place, we will enable a switcher block to easily navigate between each language.

After the language settings are done, we'll move on to translating the Drupal interface. First we will translate manually by grabbing files from localize.drupal.org, and then we'll configure the site for automatic updates. Once the contributed translations are in place, we will learn how to add and change translated UI strings as well as how to contribute these translations back to the Drupal community. The last part of the interface translation section deals with changing English strings and reusing strings on other sites.
