 # What is it?
 
 QuAcK is a small electronic structure program written in `Fortran 90` and developed at the Laboratoire de Chimie et Physique Quantiques [LCPQ](https://www.lcpq.ups-tlse.fr) (Toulouse, France).
-QuAcK is usually used for prototyping purposes and the successful ideas are usually implemented more efficiently in [quantum package](https://quantumpackage.github.io/qp2/). QuAcK is an excellent place to start for experienced PhD students or postdocs as the code is simple and written in a fairly well-known and straightforward language. For beginners, we suggest having a look at [qcmath](https://github.com/LCPQ/qcmath/), a Mathematica-based program to help newcomers in quantum chemistry easily develop their ideas.
