+# About bootstrap defaults
+
+These defaults are intended to be a good starting point for working with x.py,
+with the understanding that no one set of defaults make sense for everyone.
+
+They are still experimental, and we'd appreciate your help improving them!
+If you use a setting that's not in these defaults that you think
+others would benefit from, please [file an issue] or make a PR with the changes.
+Similarly, if one of these defaults doesn't match what you use personally,
+please open an issue to get it changed.
+
