+### Custom PodSpec Example
+
+You can provide a complete custom PodSpec to configure resource limits, additional containers, volumes, security contexts, etc:
+
+```json
+{
+  "runner_workdir": "/runner/_work/",
+  "pod_spec": {
+    "restartPolicy": "Never",
+    "containers": [
+      {
+        "name": "runner",
+        "image": "edp.buildth.ing/devfw-cicd/garm-act-runner:1",
+        "imagePullPolicy": "Always",
+        "env": [],
+        "resources": {
+          "requests": {
+            "memory": "2Gi",
+            "cpu": "1000m"
+          },
+          "limits": {
+            "memory": "4Gi",
+            "cpu": "2000m"
+          }
+        },
+        "volumeMounts": [
+          {
+            "name": "runner-dir",
+            "mountPath": "/runner"
+          }
+        ]
+      }
+    ],
+    "volumes": [
+      {
+        "name": "runner-dir",
+        "emptyDir": {}
+      }
+    ]
+  }
+}
+```
+
+**Note:** When providing a custom `pod_spec`, the environment variables required for the runner (such as `RUNNER_TOKEN`, `METADATA_URL`, etc.) are automatically injected into the first container if not already present in the custom spec. If you provide a custom PodSpec without environment variables, make sure the container configuration is compatible with the runner requirements.
+
+### Default PodSpec
+
+If no `pod_spec` is provided, the following default configuration is used:
+
+```yaml
+restartPolicy: Never
+containers:
+  - name: runner
+    image: edp.buildth.ing/devfw-cicd/garm-act-runner:1
+    imagePullPolicy: Always
+    env: [auto-generated environment variables]
+    volumeMounts:
+      - name: runner-dir
+        mountPath: /runner
+volumes:
+  - name: runner-dir
+    emptyDir: {}
+```
