 # IAM policy for projects
 
-Three different resources help you manage your IAM policy for a project. Each of these resources serves a different use case:
+Four different resources help you manage your IAM policy for a project. Each of these resources serves a different use case:
 
 * `google_project_iam_policy`: Authoritative. Sets the IAM policy for the project and replaces any existing policy already attached.
 * `google_project_iam_binding`: Authoritative for a given role. Updates the IAM policy to grant a role to a list of members. Other roles within the IAM policy for the project are preserved.
 * `google_project_iam_member`: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the project are preserved.
+* `google_project_iam_audit_config`: Authoritative for a given service. Updates the IAM policy to enable audit logging for the given service.
 
-~> **Note:** `google_project_iam_policy` **cannot** be used in conjunction with `google_project_iam_binding` and `google_project_iam_member` or they will fight over what your policy should be.

 The following arguments are supported:
 
-* `member/members` - (Required) Identities that will be granted the privilege in `role`.
+* `member/members` - (Required except for google\_project\_iam\_audit\_config) Identities that will be granted the privilege in `role`.
   Each entry can have one of the following values:
   * **user:{emailid}**: An email address that represents a specific Google account. For example, [email protected] or [email protected].
   * **serviceAccount:{emailid}**: An email address that represents a service account. For example, [email protected].
   * **group:{emailid}**: An email address that represents a Google group. For example, [email protected].
   * **domain:{domain}**: A G Suite domain (primary, instead of alias) name that represents all the users of that domain. For example, google.com or example.com.
 
-* `role` - (Required) The role that should be applied. Only one
+* `role` - (Required except for google\_project\_iam\_audit\_config) The role that should be applied. Only one
     `google_project_iam_binding` can be used per role. Note that custom roles must be of the format
     `[projects|organizations]/{parent-name}/roles/{role-name}`.
