+        Explain, in a clear and concise way, the command you ran and the result you were trying to achieve.
+        Example: "I ran `wwctl node list` to list all nodes, and ..."
+      placeholder: |
+        ```console

+      description: |
+        If Warewulf reported an error, provide the error message. If it did not
+        report an error but the output appears incorrect, provide the incorrect
+        output. If there was no error message and no output but the result is
+        incorrect, describe how it does not match what you expect.
+
+        Also include any pertinent logs from warewulfd, typically available
+        with `journalctl -u warewulfd.service`.
+      placeholder: |
+        ```console
+        $ wwctl <command1>

+        If you have any relevant configuration detail (`nodes.conf` or `warewulf.conf`, etc.) you can add that here as well.

+    attributes:
+      label: General information
+      options:
+        - label: I have run `wwctl version` and reported the contents of `/etc/os-release`

+        - label: I have searched the issues of this repo and believe this is not a duplicate

+        We encourage you to try, as much as possible, to reduce your problem to
+        the minimal example that still reproduces the issue. That would help us
+        a lot in fixing it quickly and effectively!
+
+        If you want to ask a question about Warewulf (how to use it, what it
+        can currently do, etc.), try the `#warewulf` channel on [our
+        Slack](https://warewulf.org/help) first. We have a welcoming community
+        and chances are you'll get your reply faster and without opening an
+        issue.
+        
+        Other than that, thanks for taking the time to contribute to Warewulf!
