 ## Approach / Background
 
 These tutorials are designed to be an introduction to data science.
 
-The goal is to offer hands-on materials that allow for getting started with finding and analyzing data, in order to build up to working on data-science related projects.

 These materials are in the Python programming language, and presume basic knowledge of programming and standard library Python.
 
-These tutorials also try to interface with the vast world of existing tutorials, materials, and documentation. They are explicitly designed to give a quick introduction to a topic of interest, and then link out to more comprehensive resources. In that sense, they are designed to be more like a yellow pages than an encyclopedia.
