+- setup means that DIRAC code can already be found in the current file system, and it is only a matter of invoking a rc file that would add DIRAC paths
+- configure means adding dirac specific configuration files (which, at a minimum, should include the location of a DIRAC configuration service)

 The following CS section is used for administering the DIRAC pilots::
 
-   Operations/<Setup>/Pilot
+   Operations/Defaults/Pilot
 
 These parameters will be interpreted by the WorkloadManagementSystem/SiteDirector agents, and by the WorkloadManagementSystem/Matcher.
 They can also be accessed by other services/agents, e.g. for syncing purposes.
 
 Inside this section, you should define the following options, and give them a meaningful value (here, an example is given)::
 
-   # Needed by the SiteDirector:
-   Version = v7r2p1  # DIRAC version(s)
