 # Raise a bug
 
-link to github when available
+Bugs and feature requests for IDEA are tracked on GitHub, and anyone can open one.
+
+* **Report a bug:** [open a new issue](https://github.com/cfs-energy/idea/issues/new/choose) and choose **Bug report**.
+* **Request a feature:** the same page, choose **Feature request**.
+* **Ask a question:** [GitHub Discussions](https://github.com/cfs-energy/idea/discussions).
+
+Search the [open issues](https://github.com/cfs-energy/idea/issues) first; the problem may already be known.
+
+## What to include
+
+* **The IDEA version:** the contents of `IDEA_VERSION.txt` in the release you deployed, or the `idea-administrator` image tag you ran (for example `26.09.0`).
+* **Where it happened:** the web portal, the cluster manager, the scheduler, virtual desktops, the installer or an upgrade; the base OS of the host or desktop involved; the AWS region and partition.
+* **Steps to reproduce**, what you expected, and what happened instead.
+* **The exact error text:** the message on screen for the portal, the full command output for `idea-admin.sh`.
+* **Logs from the module host** for the minutes around the failure: `/opt/idea/app/logs/application.log`. For an installer or upgrade failure, add the CloudFormation stack status and the failed resource's status reason.
+* **Screenshots** for anything visual.
+* Whether you changed IDEA from the published release, and if so what.
+
+## What not to include
+
+Issues are public. Remove credentials, tokens, account ids, private hostnames and IP addresses before pasting logs or screenshots.
+
+## Security issues
+
+Do not put exploit details in a public issue. Open an issue that says only that you have a security finding and how a maintainer can reach you, and a maintainer will follow up privately.
