+    # ## Enabling Logging
+    #
+    # To enable logging for this library, set the logger for the underlying [gRPC](https://github.com/grpc/grpc/tree/master/src/ruby) library.
+    # The logger that you set may be a Ruby stdlib [`Logger`](https://ruby-doc.org/stdlib-2.5.0/libdoc/logger/rdoc/Logger.html) as shown below,
+    # or a [`Google::Cloud::Logging::Logger`](https://googlecloudplatform.github.io/google-cloud-ruby/#/docs/google-cloud-logging/latest/google/cloud/logging/logger)
+    # that will write logs to [Stackdriver Logging](https://cloud.google.com/logging/). See [grpc/logconfig.rb](https://github.com/grpc/grpc/blob/master/src/ruby/lib/grpc/logconfig.rb)
+    # and the gRPC [spec_helper.rb](https://github.com/grpc/grpc/blob/master/src/ruby/spec/spec_helper.rb) for additional information.
+    #
+    # Configuring a Ruby stdlib logger:
+    #
+    # ```ruby
+    # require "logger"
+    #
+    # module MyLogger
+    #   LOGGER = Logger.new $stderr, level: Logger::WARN
+    #   def logger
+    #     LOGGER
+    #   end
+    # end
+    #
+    # # Define a gRPC module-level logger method before grpc/logconfig.rb loads.
+    # module GRPC
+    #   extend MyLogger
+    # end
+    # ```
     #
     module Monitoring
       module V3
