+### When coding, always use coding standards
+If you're familiar with open source software, you probably know how important coding guidelines and standards are. Most common are (in order of appearance) PEAR, Zend(Framework) and [PSR-1](http://www.php-fig.org/psr/psr-1)/[PSR-2](http://www.php-fig.org/psr/psr-2).
+
+Since the [PHP-FIG](http://www.php-fig.org) and their standards gain more and more followers and Anchor uses composer, which supports PSR-0 and PSR-4, all code should follow [PSR-1](http://www.php-fig.org/psr/psr-1) and [PSR-2](http://www.php-fig.org/psr/psr-2).
+More help on best practices for PHP development can be found on [PHP the right way](http://www.phptherightway.com).
+
+When working on a file, always enforce coding standards for the whole file. This increases the consistency of the code with every contribution!
