 ## Features addressed in this tutorial
 
   * Global quantities and their special shape functions (see picture above)
-  * Computations of the energy dual, i.e. of the armature charge of the electrode
+  * Computation of the energy dual, i.e. of the armature charge of the electrode
   * More on ONELAB parameters (flags, model options, check boxes, menus, ...)
 
 ## Additional information
 
-This is a further step on the electrostatic 2D model of a microstrip.
+This is a further step building on the electrostatic 2D model of a microstrip (tutorial 1).
 We show in this  tutorial how GetDP takes advantage of global quantities and the associated global basis functions
    * to reduce the number of unknowns
    * to deal with floating potentials
    * to compute efficiently the electrode charges, 
-     which are precisely the energy duals of the electrode voltages
-   * to provide output quantities (charges, armature voltages, capacitances, ...)
+     which are the energy duals of the electrode voltages
+   * to compute output quantities (charges, armature voltages, capacitances, ...)
      that can be immediately used in a external circuit.
