After installing Xray, you are ready to start managing tests in JIRA effectively and ensure that your project requirements get delivered right. Just follow our quick setup instructions.
Xray comes pre-configured with default values that make sense for most organizations but it has many options allowing you to adapt it to your testing process.
Since Xray uses JIRA issues, you are able to configure the issue screens and add custom fields to your test related issues, in case you want to customize it even further.
Please take a look at Project's Organisation from "Getting Started", to learn more on how to create and enable projects for Xray.
This page also explains how to setup your project, i.e. wether you want to split your requirements from your tests in distinct projects or not.
