-*Computation of the Non-negative Matrix Factorization (NMF) on CUDA capable Hardware*
+*CUDA accelerated computation of Non-negative Matrix Factorizations (NMF)*
+
+## About
+The Non-negative Matrix Factorization (NMF) was first described by *Paatero and Tapper* [1]
+and further developed by *Lee & Seung* [2]. Since then various algorithms for different needs were developed,
+such as *Alternating Hoyer Constrained Least Squared (AHCLS)* [3], *Gradient Descent Constrained Least Squares (GDCLS)* [4]
+and *Non-smooth Non-negative Matrix Factorization (nsNMF)* [5]. This library implements a set of algorithms and initialization strategies
+using the CUDA platforms. A binding to this library exists for the R language and can be found [here](https://github.com/razorx89/nmfgpu4R).

 4. For ease of usage you should define an environment variable called __NMFGPU_ROOT__ which points to the location of the installed library (the path provided to *CMAKE_INSTALL_PREFIX*).
