 ## Credits
 
 - Many thanks to [Benjamin Encz](https://github.com/Ben-G) and other ReSwift contributors for buidling original [ReSwift](https://github.com/ReSwift/ReSwift) that we really enjoyed working with.
-- Also huge thanks to [Dan Abramov](https://github.com/gaearon) for building [Redux](https://github.com/reactjs/redux) - all ideas in here and many implementation details were provided by his library.
