 ## Usage
 
-### Working with Queue Resources
-
-```go
-import (
-    queuev2 "github.com/kai-scheduler/api/scheduling/v2"
-    "github.com/kai-scheduler/api/client/clientset/versioned"
-)
-
-// Create a clientset
-config, _ := rest.InClusterConfig()
-client, _ := versioned.NewForConfig(config)
-
-// List queues
-queues, _ := client.SchedulingV2().Queues().List(context.TODO(), metav1.ListOptions{})
-```
-
-### Working with PodGroups
-
-```go
-import (
-    podgroupv2alpha2 "github.com/kai-scheduler/api/scheduling/v2alpha2"
-    "github.com/kai-scheduler/api/utilities/podgroup"
-)
-
-// Calculate preemptibility from priority
-preemptibility := podgroup.CalculatePreemptibility("", int32(50))
-// Returns v2alpha2.Preemptible (priority < 100 = preemptible)
-```
-
-### GPU Resource Utilities
-
-```go
-import (
-    "github.com/kai-scheduler/api/utilities/resources"
-)
-
-// Check if pod requests GPU fractions
-if resources.RequestsGPUFraction(pod) {
-    fraction := resources.GetGPUFraction(pod)
-    memory := resources.GetGPUMemory(pod)
-}
-
-// Extract DRA GPU resources
-gpuResources, _ := resources.ExtractDRAGPUResources(ctx, pod, k8sClient)
-```
