 The next three lines configure the SEER experiment control system.  The '''local_seer''' service will add a node named '''control''' to each experiment that is effictively invisible outside the party's area.  Computers will treat that as a SEER controller, and experimenters can connect to it directly to see and manipulate their areas.  The '''seer_master''' service adds a node named seer-master to the experiment that each area's controller will also connect to.  Connecting to the seer-master controller allows thw whole experiment to be viewed and manipulated.
 
+== Creating the Experiment ==
+
+To create the experiment:
+
+{{{
+fedd_create.py --file multi-swap-example.tcl --experiment_name=faber-multi
+}}}
+
+You can provide any identifier you like for the experiment name.
+
+This will return pretty shortly (though not instantly) with output like this:
+
+
+{{{
+localname: faber-multi
+fedid: b4339d8a339097e87ed5624a36b584fe95b0ea0d
+status: starting
+}}}
+
+The [FeddAbout#GlobalIdentifiers:Fedids fedid] is the unique name for the experiment, and the localname is a human-readable nickname.  It is derived from the suggested experiment name passes to fedd_create.py.  Generally the name passed is the one used, but if there is a name collision, fedd disambiguates.  Finally the status is given.  "Starting" means that fedd is constructing the experiment.  This is generally a process that takes 10 minutes or so, though troubles with individual nodes can make it take longer.Fedd simultaneously swaps a separate experiment in for each sub experiment.
+
+You can check on the progress of the experiment using [FeddCommands#fedd_multistatus.py fedd_multistatus.py] which prints a brief status for each federated experiment:
+
+{{{
+$ fedd_multistatus.py 
+faber-multi:b4339d8a339097e87ed5624a36b584fe95b0ea0d:starting
+}}}
+
+When the experiment is active:
+
+{{{
+localname: faber-multi
+fedid: b4339d8a339097e87ed5624a36b584fe95b0ea0d
+status: active
+}}}
+
+Experiments can also be "failed" which means it will not come up, and a couple other states.
+
+Because creation takes a while, users want to see what's going on, even if it is somewhat cryptic.  There are several ways to do this.  The [FeddCommands#fedd_spewlog.py fedd_spewlog.py] command prints the fedd swapin log to stdout and terminates when the experiment fails or activates.  For example:
+
+{{{
