 ## Project Overview
-The goal is to design and create the structure of a Book Listing app which would allow a user to get a list of published books on a given topic. You will be using the google books api in order to fetch results and display them to the user.
+The goal is to design and create the structure of a Book Listing app that allows a user to get a list of published books on a given topic. You will use the Google Books API to fetch results and display them to the user.
 
-## Why this project?
-I learned about the web and about how to get data from an api. I also learned how to parse that data and display it to a user. This project gives me the ability to practice those skills, which will be key in developing any app which makes use of a backend server, real time data, or interactions over the internet.
+## Why This Project?
+This project helps you learn about the web and how to get data from an API. You will also learn how to parse that data and display it to a user. This project is key for developing any app that makes use of a backend server, real-time data, or interactions over the internet.
 
-## What will I learn?
-This project is about combining various ideas and skills we’ve been practicing throughout the course. They include:
-
-1. Fetching data from an API
-2. Using an AsyncTask
-3. Parsing a JSON response
-4. Creating a list based on that data and displaying it to the user.

 ## Requirements
-To achieve this, I'll make use of the [Google Books API](https://developers.google.com/books/docs/v1/getting_started#intro). This is a well-maintained API which returns information in a JSON format.
-An example query that we found useful was :
-
-https://www.googleapis.com/books/v1/volumes?q=android&maxResults=1
