 ## Use
-OMFlut being built on top of OpenMDAO, any model must derive from an OpenMDAO group. The flutter calculation is carried out in the class `FlutterGroup`, which is also OpenMDAO group. The class requires four underlying builders: structural, aerodynamic, transfer scheme and flutter computation. These builders must instantiate and initialize all the components required by each individual methodology. A template for building custom builders is provided with the code and examples of already existing builders can be found in their respective repository.
+OMFlut being built on top of OpenMDAO, any model must derive from an OpenMDAO group. The flutter calculation is carried out in the class `FlutterGroup`, which is also OpenMDAO group. The class requires four underlying builders: structural, aerodynamic, transfer scheme and flutter computation. An optional geometry builder can also be provided. These builders must instantiate and initialize all the components required by each individual methodology. A template for building custom builders is provided with the code and examples of already existing builders can be found in their respective repository.
 A typical model for computing flutter will look like:
 ```python
 from omflut import FlutterGroup
 import openmdao.api as om
 class MyModel(om.Group):
   def setup(self):
+    g = GeometryBuilder(...) # optional
     s = StructuralBuilder(...)
     a = AerodynamicBuilder(...)
     x = XferBuilder(s, a, ...)
     f = FlutterBuilder(...)
-      self.add_subsystem('flutter', FlutterGroup(struct=s, xfer=x, aero=a, flutter=f))
+    self.add_subsystem('flutter', FlutterGroup(struct=s, xfer=x, aero=a, flutter=f, geo=g))
 ```
