+## Note ##
+
+We were updating this page vigorously until about 2:30 pm on Saturday 31
+January. Now it is relatively stable, but we'll tweak it as we learn more. We
+encourage you to try to get the software set up sooner rather than later, and
+those who do so first should let us know how things go---whether it's smoothly
+or not---so that we might possibly refine or expand the instructions for
+others. It'd be great if you took careful notes of what you did, step by step.
+If our instructions are broken or misleading or incomplete, and you figure out
+how to fix them on your own, it'd also be great if you can tell us what went
+wrong and exactly what you did to achieve joy.
