Decomposition.md

 Every structure should divide the information that they store across processors, in order to do this two main approach are considered inside OpenFPM.
 
-* Model decomposition
+* Model decomposition: (Steps)
+     * Domain decomposition
+     * Generate graph model
+     * Find optimal decomposition
+     * Optimizing the decomposition     
+
 * Fixed decomposition
-* Data driven decomposition
+     * Domain decomposition
 
+* Data driven decomposition
+     * Divide the total information in equal chunks
 
 The fist approach try to create a model for computation and comunication and try to find a decomposition that minimize it.
