 \section{Model-to-Model Transformations}
 
-Model-to-Model transformations are a part of model-driven engineering (MDE). These transformations involve transforming one model into another to adapt, enhance or refine it for its purpose. 
+Model-to-Model transformations are a part of model-driven engineering (MDE). These transformations involve transforming one model into another. a model is an abstraction of representation and behavior within a system.  
 
-The process of performing a model-to-model transformation is to convert one model into another, while preserving or adapting its underlying semantics and structure~\cite{ModelToModelTransformations}. 
+The process of performing a model-to-model transformation is to convert one model into another, while preserving or adapting its underlying semantics and structure~\cite{ModelToModelTransformations}. This is usually done by traversing its structure, and extracting data and transforming its format to fit the model it should be transformed into. This allows a model described within one domain to be transformed into another automatically. 
 
 
-This is quite similar to what our tool described in this thesis is doing.

+This is quite similar to what our tool described in this thesis is doing. We are transforming the AST of the user code from one AST definition not using a proposal, so one form of representation, into another using a proposal not part of the original AST.
