 Welcome to Selenite! Selenite is an initiative to provide geoscientists around the world with a powerful graphical interface for using GEOS, a massively parallelized multiphysic simulation framework.
 
+## Two interfaces
 Selenite consists of two interfaces, Selenite Simple and Selenite Advanced.
 
-Selenite Simple aims to be a simplified interface which aims to make using GEOS as simple as picking a few components and changing a few parameters.
+### Selenite
+Selenite (or Selenite Simple) aims to be a simplified interface which aims to make using GEOS as simple as picking a few components and changing a few parameters.
 
+### Selenite Advanced
 On the other hand, Selenite Advanced aims to provide users with a powerful and limitless way to create GEOS input files using visual programming. 
 
+### Data sharing
 The two interfaces are connected and can share configuration blocks (macro blocks). For instance, if in Selenite Simple you end up missing a feature, all you have to do is to use Selenite Advanced to create a macro block that will then be available in the simplified interface.
