 ### Configuration
 
 The path to the **Credentials JSON** file can be configured instead of storing
 it in an environment variable. Either on an individual client initialization:
 
 ```ruby
 require "google/cloud/dataplex/v1"
 
-client = ::Google::Cloud::Dataplex::V1::MetadataService::Client.new do |config|
+client = ::Google::Cloud::Dataplex::V1::ContentService::Client.new do |config|
   config.credentials = "path/to/keyfile.json"
 end
 ```
 
 Or globally for all clients:
 
 ```ruby
 require "google/cloud/dataplex/v1"
 
-::Google::Cloud::Dataplex::V1::MetadataService::Client.configure do |config|
+::Google::Cloud::Dataplex::V1::ContentService::Client.configure do |config|
