Let's get started with the actual code now. On your machine where you have installed all your dependencies, create a new folder named SmartExchange. Open Command Prompt or Terminal inside that folder. Navigate to https://github.com/PacktPublishing/getting-started-with-google-cloud-ai-services and you should find a folder in this repository named Chapter 2\code\smart-exchange-base.
If you would like, you can download the entire repository that consists of completed code chapter by chapter, or you can explicitly download the code of one folder using a service such as GitZip. To use GitZip, head over to http://kinolien.github.io/gitzip/ and paste https://github.com/PacktPublishing/Getting-Started-with-Google-Cloud-AI-Services/tree/master/Chapter%202/code/smart-exchange-base%20 ...
