 When a workspace is started, DWO reads the corresponding {devworkspace} CR and creates the necessary resources such as deployments, secrets, configmaps, routes such that at the end a workspace pod representing the development environment defined in the devfile is created.
 
+== {devworkspace} Operator version requirements
+
+{prod-short} requires a minimum version of the {devworkspace} Operator to function correctly. The operator enforces this requirement through two validation gates:
+
+.Validation gates
+[cols="1,2,2",options="header"]
+|===
+| Gate | When it occurs | Behavior
+
+| Webhook validation
+| CheCluster CR creation
+| Prevents CheCluster creation if the {devworkspace} Operator is not installed. Returns error: `DevWorkspace Operator is not installed. Please install it before creating a CheCluster instance`
+
+| Reconciler version validation
+| CheCluster reconciliation
+| Blocks reconciliation if the installed {devworkspace} Operator version is below the minimum required version. Logs error and updates CheCluster status with message: `DevWorkspace Operator version <installed-version> is installed, but Eclipse Che requires version <minimum-version> or higher. Please upgrade the DevWorkspace Operator`
+|===
+
+IMPORTANT: The current minimum required {devworkspace} Operator version is 0.38.0. This requirement is validated at runtime rather than through package manager dependencies.
+
+.Verification
+
+To verify the installed {devworkspace} Operator version on OpenShift:
+
+[source,bash,subs="+quotes,+attributes"]
+----
+{orch-cli} get subscription -A -o json | jq -r '.items[] | select(.spec.package=="devworkspace-operator") | .status.installedCSV'
+----
+
+The output shows the installed Cluster Service Version (CSV), for example: `devworkspace-operator.v0.40.0`.

 ====
 The {prod} Operator depends on the {devworkspace} Operator. If you install the {prod} Operator manually to a non-default namespace, ensure that the {devworkspace} Operator is also installed in the same namespace. The Operator Lifecycle Manager installs the {devworkspace} Operator as a dependency within the {prod} Operator namespace. If the {devworkspace} Operator is already installed in a different namespace, two conflicting installations can result.
+
+{prod-short} requires {devworkspace} Operator version 0.38.0 or higher. The {prod-short} Operator validates this requirement at runtime and blocks CheCluster creation or reconciliation if the requirement is not met.
