+        ## Use of AI in bug reports
+
+        AI tools are good at carrying out well-defined tasks, but they are not good at troubleshooting.
+        Please do NOT paste an AI-generated wall of text into the issue template - if the AI hasn't solved
+        your problem, its wild guesses are not likely to help.
+
+        Please DO include your own words and observations, compile/boot logs, and
+        especially a minimal reproducible example of your YAML configuration that demonstrates the problem.
+
+        It is however quite acceptable to use AI to translate your *own* report,
+        if you aren't a competent English speaker.
+
+        If you really think it will be useful to include an AI's analysis, preferably wrap it in a `<details>` block which will be collapsed by default.
+
+        If you are using AI to help solve a problem, rather than asking it to speculate about what the problem is,
+        it can be more useful to ask it to create a step-by-step troubleshooting procedure.
+        AI is also useful for generating boilerplate code, such as a minimal reproducible example of your YAML
+        configuration that demonstrates the problem.
+
+        Used properly, AI can be a useful tool to help you solve your problem, but don't let it get in the way.
