Currently there exists a number of different links within our knowledge base in regards to integrating JIRA with Perforce.  Previous incarnations of this integration used a now deprecated plugin for JIRA.  In the current state, JIRA requires the use of Fisheye in order to integrate Perforce with JIRA.   It would help if there was a more clear distinction between these two different integration methods to help clarify which documented steps apply to which configuration and which do not.

While there does exist some screenshot to help explain how this integration can be configured over on https://ecosystem.atlassian.net/wiki/display/FISH/Mapping+Custom+Fields  Those screenshots appear to have been created back in JIRA 3.x or 4.x, and it would help to have an updated visual explanation of how this can be configured in both current JIRA and current Perforce.
