+Internationalization
+====================
+
+Internationalization (I18N) refers to the process of designing a software application so that it can be adapted to
+various languages and regions without engineering changes. For Web applications, this is of particular importance
+because the potential users may be worldwide.
+
+When developing an application it's assumed that we're relying on
+[PHP internationalization extension](http://www.php.net/manual/en/intro.intl.php). While extension covers a lot of aspects
+Yii adds a bit more:
+
+- It handles message translation.
