 Device detection in Varnish
 ===========================
 
+
+Maintainers wanted
+------------------
+
+This VCL set was originally collected from some Norwegian newspapers and other
+media sites in 2011/2012. It serves as a good starting point for doing device
+detection in Varnish.
+
+**We are currently looking for a new maintainer.**
+
+Work load is maybe one pull request per month, as well as figuring out where to
+take the VCL file set over time.
+
+The main issue with the current maintenance level is that we (Varnish Software)
+don't run any big applications on Varnish production ourselves, so we don't see
+the client mix changing. This means that the VCL set most likely will be less
+and less useful in real life, as old crap and assumptions are left to rot in
+here.
+
+Any new maintainer(s) should probably be running this VCL in production, or do
+similar/related work close to backend applications. Contact
+<lkarsten@varnish-software.com> to discuss this further.

 code only.
