Cocoa is a big box of chocolate, but instead of eating it, people use it to do important work on the computer. This special kind of chocolate is used by people who study things like history, literature, art, and other types of culture. They use the cocoa to help them find and organize information so they can learn more about their subjects.
Imagine you have a big box of toys, but you don't know where to find your favorite toy. That's where cocoa comes in! Cocoa helps you sort through all the toys and find what you're looking for. In the same way, people use cocoa to sort through lots of information and find important things they need to know.
It's kind of like a treasure hunt. You have a big map with lots of clues and you use those clues to find the treasure. Cocoa helps people find the clues they need to piece together important information about the culture they're studying.
