+## A Note About Compiler Versions
+
+The Zig language is under very active development. Ziglings will attempt to
+be current, but not bleeding-edge. However, sometimes fundamental changes
+will happen. Ziglings will check for a minimum version and build number
+(which is this one: `0.x.x-dev.<build number>`) and exit if your version of
+Zig is too old. It is likely that you'll download a build which is greater
+than the number in the example shown above in this README.  That's okay!
+
+Once you have a version of the Zig compiler that works with your copy of
+Ziglings, they'll continue to work together forever. But if you update one,
+keep in mind that you may need to also update the other.
