Interface translation depends on the Locale module, which should already be enabled on your site once you have installed a translation.
In the administrative toolbar, click Configuration?“Translate interface” in the “Regional and language” section (admin/config/regional/translate) to get started.
You will be presented with a table of your languages and the percentage of strings that have been translated so far. Click on the Translate tab (admin/config/regional/translate/translate).
The “String contains” search box, pictured in Figure 8-15, allows you to search for a specific piece of text somewhere in Drupal’s interface and then translate it.
