 ## Design Details
 
 ### Workload Slices
-To support horizontal scaling of jobs, we will introduce the concept of a "Workload Slice”. A Workload Slice is a Workload object  with an owner reference to the original Workload for a job. Workload Slices represent per-replica changes to a job that were not initially accounted for when the job was created.
+To support horizontal scaling of jobs, we will introduce the concept of a "Workload Slice”. A Workload Slice is a Workload object  with an owner reference to the original Workload for a job. Workload Slices represent per-replica changes to a job that were not initially accounted for when the job was created. **It's an internal state, not an extra CRD.**
 
 The benefit of Workload Slices is that Kueue can evaluate admission on a per-replica basis without changing the existing semantics of the Workload API. Once a Workload Slice is admitted, it will be garbage collected and its resources will be aggregated into the admission status of the parent workload.
 - Workload Slices will be submitted to the same LocalQueue that's referenced by the top-level Workload.
