+**How to set a Dynamic Workflow using the Temporal Go SDK**
+
+A Dynamic Workflow in Temporal is a Workflow that is invoked dynamically at runtime if no other Workflow with the same name is registered.
+A Workflow can be registered as dynamic by using `worker.RegisterDynamicWorkflow()`.
+You must register the Workflow with the Worker before it can be invoked.
+Only one Dynamic Workflow can be present on a Worker.
+
+The Workflow Definition must then accept a single argument of type `converter.EncodedValues`.
+This code snippet is taken from the [Dynamic Workflow example from samples-go](https://github.com/temporalio/samples-go/tree/main/dynamic-workflows).
+
+```go
+func DynamicWorkflow(ctx workflow.Context, args converter.EncodedValues) (string, error) {
+	var result string
+	info := workflow.GetInfo(ctx)
+
+	var arg1, arg2 string
+	err := args.Get(&arg1, &arg2)
+	if err != nil {
+		return "", fmt.Errorf("failed to decode arguments: %w", err)
+	}
+
+	if info.WorkflowType.Name == "dynamic-activity" {
+		ctx = workflow.WithActivityOptions(ctx, workflow.ActivityOptions{StartToCloseTimeout: 10 * time.Second})
+		err := workflow.ExecuteActivity(ctx, "random-activity-name", arg1, arg2).Get(ctx, &result)
+		if err != nil {
+			return "", err
+		}

+**How to set a Dynamic Activity using the Temporal Go SDK**
+
+A Dynamic Activity in Temporal is an Activity that is invoked dynamically at runtime if no other Activity with the same name is registered.
+A Workflow can be registered as dynamic by using `worker.RegisterDynamicActivity()`.
+You must register the Activity with the Worker before it can be invoked.
+Only one Dynamic Activity can be present on a Worker.
+
+The Workflow Definition must then accept a single argument of type `converter.EncodedValues`.

+```go
+func DynamicActivity(ctx context.Context, args converter.EncodedValues) (string, error) {
+	var arg1, arg2 string
