+        Please provide steps to reproduce this bug, with the smallest possible
+        set of source files. For normal bugs this should ideally be one 
+        ``index.rst`` file, and for ``sphinx.ext.autodoc`` bugs, this should
+        ideally be a single ``index.rst`` file, and a single example Python 
+        module.

+        Minimal method (you can also paste the contents of ``index.rst`` and
+        ``conf.py`` into this report):
+        ```bash
+        $ echo "Content demonstrating the bug..." > index.rst
