+## Operations enable operational workflows
+
+Crossplane v2 introduces Operations - a new way to run operational tasks using
+function pipelines.
+
+Operations handle tasks that don't fit the typical resource creation pattern.
+Things like certificate monitoring, rolling upgrades, scheduled maintenance, or
+responding to resource changes.
+
+**Operations run function pipelines to completion, like a Kubernetes Job.**
+Instead of continuously managing resources, they perform specific tasks and
+report the results.
+
+```yaml
+apiVersion: ops.crossplane.io/v1alpha1
+kind: CronOperation
+metadata:
+  name: cert-monitor
+spec:
+  schedule: "0 6 * * *"  # Daily at 6 AM
+  mode: Pipeline
+  pipeline:
+  - step: check-certificates
+    functionRef:
+      name: crossplane-contrib-function-python
+    # function checks SSL certificates and reports status
+```
+
+Operations support three modes:
+
+* **Operation** - Run once to completion
+* **CronOperation** - Run on a scheduled basis  
+* **WatchOperation** - Run when resources change
+
+Operations can read existing resources and optionally change them. This enables
+workflows like annotating resources with operational data, triggering
+maintenance tasks, or implementing custom operational policies.
