 This section provides some tips and tricks about triaging issues submitted to the Jenkins core.
 
 === Issue tracker structure
 
-Jenkins core uses the link:https://issues.jenkins.io/projects/JENKINS[JENKINS] project for issue tracking.
-This project is shared between the Jenkins core components and plugins,
-and the Jenkins core is scattered across multiple components: `core`, `remoting`, `cli`, `winstone-jetty`, etc.

 === How to discover untriaged issues?
 
 * Community rating in Jenkins link:https://www.jenkins.io/changelog/[Regular (Weekly)]
   and link:https://www.jenkins.io/changelog-stable/[LTS] releases.
   Such ratings allow users to reference issues they experienced with new Jenkins core releases,

 * **Verify the issue type**.
   `Bug` should be used for bug reports.

   Some labels can be found in similar issues or documentation linked from system log entries in the reports.
 * **Move security issue** to the `SECURITY` project.
   Sometimes the issue reporters do not follow the link:https://www.jenkins.io/security/#reporting-vulnerabilities[vulnerability reporting] process and report security issues in public.
-  If you see such issues, move them to the `SECURITY` project so that the security team takes care of their triage.

+  If you see such issues, request a core maintainer to delete the issue and re-report it to the `SECURITY` project so that the security team takes care of their triage.
 * **Label regressions and CC stakeholders** if an issue is reported as a regression with a clear root cause,
   please set a `regression` label and, if applicable, CC contributors of a change that led to the regression.
 * **Resolve invalid issues and support requests**.

-=== Resolving vs. Closing issues
-
-Jira workflow for the `JENKINS` project has two similar states: `Resolved` and `Closed`.
-Historically the issues are rarely being **closed**, and all dashboard and Jenkins processes interpret resolved issues as closed.
-The main difference is that the _Resolved_ issues can be reopened by users while _Closed_ ones can be reopened by admins only.

-For triage purposes, it is recommended to use the `Resolved` state if there is a chance that the issue will be reopened by the reporter or other contributor
