+Pay attention: This is NOT an official Archlinux repository! You probably
+should neither trust nor use the packages contained in this repository.
+
+This is a private repo for my own systems to pull pre-built packages from,
+therefore packages can and will vanish, get modified or added. Basically
+don't rely on anything in here!
+
+If you want to setup your own repository refer to these resources:
