 You can use the `Query()` function as a reference to the last connected database. E.g.
 
+```php
 Query()->get('table_name');
+```
 
 or
 
+```php
 $result = Query()->query($sql);

 If the `alias` key is set in the parameters, you can refer to a specific database connection
 
+```php
 // Set the alias in the connection parameters
 $params['alias'] = 'old';
 
 // Connect to the legacy database
 Query('old')->query($sql);

 ### Running Queries
 Query uses the same interface as CodeIgniter's [Active Record class](http://ellislab.com/codeigniter/user-guide/database/active_record.html). However, it does not implement the `update_batch` or caching methods.

 ### Inserting / Updating
 
 An example of an insert query:
-
+```php
 $query = $db->set('foo', 'bar')
 	->set('foobar', 'baz')
 	->where('foo !=', 'bar')
 	->insert('table');

 An example of an update query:
 
+```php
 $query = $db->set('foo', 'bar')
 	->set('foobar', 'baz')
 	->where('foo !=', 'bar')
 	->update('table');
+```
 
 The `set` method can also take an array as a paramater, instead of setting individual values.
