Server was setup at http://reading-web-staging.wmflabs.org/wiki/Special:MobileDiff/9 by updating the vagrant image and enabling the mobile diff. The steps below are kind of invalid now:
~~* [] Create a server that has the current wikidiff2 library deployed. to use WMF's #readers-web-backlog team can see and use the most current code base. #readers-web-backlog should then be able to use this server as their test server, making all the changes to it that they need.~~
~~** This should be a virtual machine with the same setup we have on our test servers~~
~~* [] Add the mobile frontend extension~~
~~* [] Add the mobile skin~~
~~* [] Add necessary configuration that's needed for testing the new mobile diff behavior~~
~~* [] Give access to all people that have access to the test server as described in {T187801}~~
~~* [] Remove the test server on toollabs, which was created in {T187801}~~
