 ## Quickstart
 
 
 If you are using Maven, add this to your pom.xml file:
 
+
 ```xml
 <dependency>
   <groupId>com.google.cloud</groupId>
   <artifactId>google-cloud-binary-authorization</artifactId>
-  <version>0.2.0</version>
+  <version>0.2.1</version>
 </dependency>
 ```
 
 If you are using Gradle without BOM, add this to your dependencies
+
 ```Groovy
-compile 'com.google.cloud:google-cloud-binary-authorization:0.2.0'
+compile 'com.google.cloud:google-cloud-binary-authorization:0.2.1'
 ```
 
 If you are using SBT, add this to your dependencies
+
 ```Scala
-libraryDependencies += "com.google.cloud" % "google-cloud-binary-authorization" % "0.2.0"
+libraryDependencies += "com.google.cloud" % "google-cloud-binary-authorization" % "0.2.1"
 ```
 
 ## Authentication
 
 See the [Authentication][authentication] section in the base directory's README.
 
+## Authorization
+
+The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired Binary Authorization APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the Binary Authorization API calls.
