-### Supported Ruby Versions
-
-This library is supported on Ruby 2.0+.
-
-However, Ruby 2.3 or later is strongly recommended, as earlier releases have
-reached or are nearing end-of-life. After June 1, 2018, Google will provide
-official support only for Ruby versions that are considered current and
-supported by Ruby Core (that is, Ruby versions that are either in normal
-maintenance or in security maintenance).
-See https://www.ruby-lang.org/en/downloads/branches/ for further details.

+## 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
+```
+
+## Supported Ruby Versions
+
+This library is supported on Ruby 2.3+.
+
+Google provides official support for Ruby versions that are actively supported
+by Ruby Core—that is, Ruby versions that are either in normal maintenance or
+in security maintenance, and not end of life. Currently, this means Ruby 2.3
+and later. Older versions of Ruby _may_ still work, but are unsupported and not
+recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details
+about the Ruby support schedule.
