 # Why Use Data-Transport ?
 
-Data transport is a simple framework that:
+Data transport is a simple framework that enables read/write to multiple databases or technologies that can hold data. In using **data-transport**, you are able to:
-- easy to install & modify (open-source)
-- enables access to multiple database technologies (pandas, SQLAlchemy)
-- enables notebook sharing without exposing database credential.
-- supports pre/post processing specifications (pipeline)
 
+- Enjoy the simplicity of **data-transport** because it leverages SQLAlchemy & Pandas data-frames.
+- Share notebooks and code without having to disclosing database credentials. 
+- Seamlessly and consistently access to multiple database technologies at no cost
+- No need to worry about accidental writes to a database leading to inconsistent data
+- Implement consistent pre and post processing as a pipeline i.e aggregation of functions
+- **data-transport** is open-source under MIT License https://github.com/lnyemba/data-transport
