 ## Choosing the boundaries conditions
 
-In the configuration file, set the property Disk.Boundaries with a coma separated list of names of the boundaries conditions you want to apply:
+Each type of boundaries conditions are identified by a name. 
+
+To indicate what boundaries conditions you want to apply, just set the property **Disk.Boundaries** with a coma separated list of their names:
+
 ```
 Disk {
  ....
@@ -9,10 +12,18 @@ Disk {
 }
 ```
 
+**FargOCA** will then invoke those boundaries condition at predefined place in the code.
+<!-- Might want to develop -->

 ## Adding new boundaries conditions
 
 Examples of boundaries condition can be found in the the [src/boundariesConditions.cpp](https://gitlab.oca.eu/DISC/fargOCA/blob/master/src/boundariesConditions.cpp).
 
 Adding a new boundary condition is a 2 step process, you need to:
- 1. Implement the boundary condition code.
- 2. Tell the system what is the name of that boundary condition.
+ 1. Implement the new boundary condition code.
