+## Thanks
+
+I deeply appreciate the help of the following people.
+
+- [Teemperor](https://github.com/Teemperor) implemented CMake support and lcov integration and realized escape handling in the string parser.
+- [elliotgoodrich](https://github.com/elliotgoodrich) fixed an issue with double deletion in the iterator classes.
+- [kirkshoop](https://github.com/kirkshoop) made the iterators of the class composable to other libraries.
