What you need for this book
ServiceNow is an enterprise SaaS platform. In order to work with the application, you will need access to a ServiceNow instance, with system administrator access. The examples in this book are about a custom application, but it is strongly recommended that any work be performed in a sub-production instance.
The best way to work through the book is with a developer instance. By signing up to the free program, you can get a fully capable instance that lets you work through all the examples. You can sign up at https://developer.servicenow.com/. Alternatively, contact your ServiceNow representative and request a temporary sandbox instance.
To make use of the source control integration and quickly download the code for each chapter, you will need a free GitHub account. Sign up at https://www.github.com.
The examples have all been built with the Helsinki version of ServiceNow, released in mid-2016. The concepts of ServiceNow are relevant for every version, but it is strongly recommended that you follow along with a Helsinki instance.
