+### Protect Babel
+
+The protect script seen here is to throw errors if someone ever tries to
+include internal babel files in their script. If you need something to be
+exposed, you should ask for it, not try to hack your way into getting it.
+
+### External Helpers
+
+You'll also find the script for building the external helpers file, this is
+the Babel "runtime" where all helper functions go instead of the top of a file.
