+Welcome to the service directory!
+
+This is currently under construction. I haven't
+even run these scripts yet, but I'm working on
+a sweet little perma-live process for tavernbot,
+which will make updating it super easy. 
+
+For now, these random scripts will sit here
+with no indication whatsoever as to how they
+should be used. Documentation and tested
+versions of the scripts coming soon!
+
+Cheers.
