I want to thank all who motivated me and allowed me to spend time on this book, time that I was supposed to spend with them. My first thank you is to my wife, Shuby Arora, for her support in all ways. Then, I would like to thank my little angel, Aarchi Arora. A great thanks to my parents whose blessings are always with me; this is because of them. I would like to thank the entire Packt team, especially Vikas Tiwari, Diwakar Shukla, and Denim Pinto for their overnight support. A great thank you to Shivprasad Koirala for his in-depth knowledge and his suggestions to improve various sections of the book.
