+Building an application
+===============================
+
+The goal of these notes is to give a practical
+introduction to the development of a code that uses the TRIQS headers and
+libraries. Rather than being completely general this tutorial will guide you
+through the development of a simple CT-INT impurity solver.
+
+At first, we will see how to write a code that uses TRIQS but that is not meant
+to become part of TRIQS. This is especially relevant when you write a pure C++
+code for your personal use. You will learn how to write a Monte Carlo
+simulation with a simple example.
+
+The next step will be to *pythonize* your code. This is very convenient to
+change parameters or do simple pre-simulation calculations. It is also
+the way most of TRIQS applications are done.
