-## A Simple Example
+## Quick Start
 
 We use the MNIST Addition task as a quick start example. In this task, pairs of MNIST handwritten images and their sums are given, alongwith a domain knowledge base which contain information on how to perform addition operations. Our objective is to input a pair of handwritten images and accurately determine their sum.
