+The topography of the model is defined as a set of elevation
+ values on a regular 2D grid. It is also posible to
+define interfaces between the layers of the model in the same way. 
+
+The file \texttt{meshfem3D/DATA/interfaces.dat} contains the settings of the topography grid
+and of the interfaces grids. The number 
+of interfaces, including the topography, needs to be set at the first line. Then, from the bottom 
+to the top of the model, you need to define the grids with several parameters :
+ number of points along $x$ and $y$, minimal $x$ and $y$ coordinates, spacing between points and the file 
+where the elevation values are stored. At the end of this file, you simply need to set the
+number of spectral elements in the vertical direction for each layer.
+
 Finally, you need to provide a file that tells MPI what compute nodes
 to use for the simulations. The file must have a number of entries
 (one entry per line) at least equal to the number of processors needed
