 ## Why D?
 
-[D](http://www.d-lang.,org) is a language that suits parallel programming
-because  the compiler provides certain guarantees. The D programmming language is both a low and high-level
-hybrid object orientated and functional (OOP/FP) programming language. D provides a templating/generics features that are
-far easier than that of C++. Few languages if any matches these set of features.
