-kwant - Quantum transport simulation
-====================================
+kwant, a package for tight binding models
+=========================================
 
-kwant is a Python package for numerical quantum transport calculations.  It aims
-to be an user-friendly, universal, and high-performance toolbox for the
-simulation of physical systems (of any dimensionality and geometry) that can be
-described by a tight-binding model.  kwant has been designed such that the
-natural concepts of the theory of quantum transport (lattices, symmetries,
-electrodes, orbital / spin / electron-hole degrees of freedom) are exposed in a
-simple and transparent way: Defining a new simulation setup is very close to
-describing the corresponding mathematical model.  kwant offers direct support
-for calculations of transport properties (conductance, noise, scattering
-matrix), dispersion relations, modes, wave functions, various Green's functions,
-and out-of-equilibrium local quantities (charge or current densities).  Other
-computations involving tight-binding Hamiltonians can be implemented easily
-thanks to its extensible and modular nature.
+**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.
