-## Model order reduction for Residual distribution code
+## Model order reduction for Residual distribution code with calibration
 
+This code provides a Greedy POD EIM approach to solve model order reduction tasks.
 
+The Greedy search is done in parameter space, the POD in time space and the EIM procedure is needed to interpolate the non linear fluxes.
 
+The solver used are based on residual distribution technique.
+
+Hopefully, we will be able to add a calibration process to reshape the function in time such that physical waves coincide.
