 Apart from the above, we want to add support for the following:
 * Running the deployment process in a pod: In future, we can run the deployment process in a pod. Then users can define their own custom deployments and we can run it using the image name.
-* More DeploymentTypes: https://github.com/openshift/origin/blob/master/examples/deployment/README.md#deployment-types lists most commonly used ones.
+* More DeploymentStrategyTypes: https://github.com/openshift/origin/blob/master/examples/deployment/README.md#deployment-types lists most commonly used ones.
 * Triggers: Deployment will have a trigger field to identify what triggered the deployment. Options are: Manual/UserTriggered, Autoscaler, NewImage.
 * Automatic rollback on error: We want to support automatic rollback on error or timeout.
