+Numerics of tight binding models made easy
+==========================================
+
+kwant is a Python package for numerical calculations on tigh-binding models
 with most focus on quantum transport.  It is designed to be flexible, easy to
 use, while not sacrificing performance.
 
 Its flexbility is illustrated below by showcasing some of its applications. How
 easy it is to use is shown in the tutorial, and finally its performance was
 carefully tested.

+
+Various applications of kwant:
+* conductance of a Corbino disk in a quantum Hall regime
+* A piece of bilayer graphene lattice
+* Density of states in a chaotic stadium billiard
+* A quantum wire with a proximity superconductor, and the Majorana states
+  in its spectrum.
