 Block 8 are committed to PHPCI being a truly free and open source project, providing easy to use continuous integration and testing to as many developers as possible. We may, at our sole discretion, provide paid services based upon PHPCI - but PHPCI will always remain free (as in cost, and freedom) and open source.
 
 ### The Contribution Process
