I currently set up a project in Jira. After setup the same I installed x-ray. Now there is the issue that:
Xray Custom Fields Not Configured
This section cannot be displayed because some required custom fields are not configured.
Please make sure this project is using an "Issue Type Screen Scheme" which contains the Xray Screen Schemes. In order for Xray custom fields to be editable, they must configured for this issue type's CREATE/EDIT screen.
How to do this? Where can I find a step by step documentation which explains this stuff?
