 #### Validate workflow definitions
 
 The sdk provides a way to validate if a workflow object is compliant with the serverlessworkflow specification.
 
-`WorkflowValidator` class provides two methods: 
-
-- `isValid(): boolean`
-
-```typescript
-
-const isValid = new WorkflowValidator(workflow).isValid();
-
-```
-
-- `validate(): ValidationErrors`
+`validators` provides a map of validation functions: 
 
 ```typescript
-
-const validationErrors = new WorkflowValidator(workflow).validate();
-validationErrors.errors().forEach(error => console.error(error.message()))
-
-
-```
+const validate = validators.get('WorkflowJson');
+const isValid = validate(workflow);
+if (!isValid) {
+  validate.errors.forEach(error => console.error(error.message));
+}
+```
