@@ -5,7 +5,7 @@ PHPWord is built by the crowd and for the crowd. Every contribution is welcome;
 We want to create a high quality document writer and reader library that people can use with more confidence and less bugs. We want to collaborate happily, code joyfully, and get alive merrily. Thus, below are some guidelines, that we expect to be followed by each contributor.
 
 - **Be brief, but be bold**. State your issues briefly. But speak out your ideas loudly, even if you can't or don't know how to implement it right away. The world will be better with limitless innovations.
-- **Follow PHP-FIG standards**. We follow PHP Standards Recommendations (PSRs) by [PHP Framework Interoperability Group](http://www.php-fig.org/). If you're not familiar with these recommendations, please [familiarize yourself now](https://github.com/php-fig/fig-standards). Also, please, use [PHPCodeSniffer](http://pear.php.net/package/PHP_CodeSniffer/) to validate your code against these standards.

 - **Test your code**. Nobody else knows your code better than you. So please, test your own code before submitting your pull request. PHPWord uses [PHPUnit](http://phpunit.de/) as our testing framework.
 - **Request pull in separate branch**. Do not submit your request to the master branch. But create a separate branch named specifically for the issue that you addressed. Read [GitHub manual](https://help.github.com/articles/using-pull-requests) to find out more about this. If you are new to GitHub, read [this short manual](https://help.github.com/articles/fork-a-repo) to get yourself familiar with forks and how git works in general. [This video](http://www.youtube.com/watch?v=-zvHQXnBO6c) explains how to synchronize your Github Fork with the Branch of PHPWord.
