 ### Overview of Limit Range
 
-- The administrator creates one `LimitRange` in one namespace.
+- The administrator creates one LimitRange in one namespace.
 - Users create resources like Pods, Containers, and PersistentVolumeClaims in the namespace.
 - The `LimitRanger` admission controller enforces defaults and limits for all Pods and Containers that do not set compute resource requirements and tracks usage to ensure it does not exceed resource minimum, maximum and ratio defined in any LimitRange present in the namespace.
 - If creating or updating a resource (Pod, Container, PersistentVolumeClaim) that violates a LimitRange constraint, the request to the API server will fail with an HTTP status code `403 FORBIDDEN` and a message explaining the constraint that have been violated.
