 Scaling out

 So far, we have used SkyPilot's CLI to submit work to and interact with a single cluster.
 When you are ready to scale out (e.g., run 10s or 100s of jobs), SkyPilot supports two options:
 
-- Queue jobs on one or more clusters with ``sky exec`` (see :ref:`Job Queue <job-queue>`); or
+- Queue many jobs on your cluster(s) with ``sky exec`` (see :ref:`Job Queue <job-queue>`);
 - Use :ref:`Managed Spot Jobs <spot-jobs>` to run on auto-managed spot instances
   (users need not interact with the underlying clusters)
