-When crunch-dispatch-slurm invokes @sbatch@, you can add switches to the command by specifying @SbatchArguments@. You can use this to send the jobs to specific cluster partitions or add resource requests. Set @SbatchArguments@ to an array of strings. For example:
+crunch-dispatch-slurm adjusts the "nice" values of its SLURM jobs to ensure containers are prioritized correctly relative to one another. This option tunes the adjustment mechanism.
+* If non-Arvados jobs run on your SLURM cluster, and your Arvados containers are waiting too long in the SLURM queue because their "nice" values are too high for them to compete with other SLURM jobs, you should use a smaller PrioritySpread value.
+* If you have an older SLURM system that limits nice values to 10000, a smaller @PrioritySpread@ can help avoid reaching that limit.
+* In other cases, a larger value is beneficial because it reduces the total number of adjustments made by executing @scontrol@.
+
+The smallest usable value is @1@. The default value of @10@ is used if this option is zero or negative. Example:
