+### Database
+
+Edit the file `config/db.php` with real data, for example:
+
+```php
+return [
+	'class' => 'yii\db\Connection',
+	'dsn' => 'mysql:host=localhost;dbname=yii2basic',
+	'username' => 'root',
+	'password' => '1234',
+	'charset' => 'utf8',
+];
+```
+
+**NOTE:** Yii won't create the database for you, this has to be done manually before you can access it.
+
+Also check and edit the other files in the `config/` directory to customize your application.
