+Running Different Experiments in the Same Allocation
+====================================================
+
+The ``benchpark aggregate`` command provides the functionality to batch experiments from
+the same workspace or multiple workspaces together. To use ``benchpark aggregate``,
+provide a destination for the job script, and the workspaces as positional arguments:
+
+::
+
+    $ benchpark aggregate --dest agg/ workspace1/ workspace2/ ...
+
+Then, submit the newly created job script to the scheduler:
+
+::
+    $ flux batch agg/0.sh
+
+Output from the experiments will still be written to the respective experiment
+directory.
+
 Once you have run your experiment you can try :doc:`analyze-experiment`.
