 Introduction
 ============
 
-This section describes fine-grained permissions management for your Enterprise Router resources. If your account does not need individual IAM users, you may skip this section.
+This topic describes fine-grained permissions management for your Enterprise Router resources. If your account does not need individual IAM users, you may skip this topic.
 
 By default, new IAM users do not have any permissions assigned. You need to add a user to one or more groups, and assign policies or roles to these groups. The user then inherits permissions from the groups. After authorization, the user can perform specified operations on cloud services based on the permissions.
 
-An account has all of the permissions required to call all APIs, but IAM users must be assigned the required permissions. The permissions required for calling an API are determined by the actions supported by the API. Only users who have been granted permissions can call the API successfully. For example, if an IAM user wants to query enterprise routers using an API, the user must have been granted permissions that allow the **er:instances:list** action.
