 Adblock Plus infrastructure
 ===========================
 
 The Adblock Plus infrastructure uses [Puppet](http://puppetlabs.com/)
 to set up servers, and to have a realistic development environment.
 
 Our Puppet manifests are only tested with Ubuntu 12.04 right now.

 Here _serveradmin_ is your user account on the servers, it will be used to
 run Puppet on the servers via SSH (sudo privilege required). You can list any
 host groups defined in _manifests/monitoringserver.pp_ or individual servers.
 You can also use _-v_ flag to see verbose Puppet output or _-t_ flag to do a
 dry run without changing anything.
 
 Monitoring

-Monitoring is fully functional in the development environment:

+Monitoring is fully functional in any environment, including development.
+Here, after bootstrapping the `server4` box, one can access the Nagios GUI
+from the host machine via <https://nagiosadmin:nagiosadmin@10.8.0.99/>.
 
-User name and password are both _nagiosadmin_.
+The monitoring service of our production environment, however, is accessible
+via <https://monitoring.adblockplus.org/>.
+Add yourself to _files/nagios-htpasswd_ in the _private_ module used on the
+server, or have someone add you if you don't have access.
