-#### Verbose Logging
+#### Logging
+
+##### Errors
+
+By default, `ruby-openai` logs any `Faraday::Error`s encountered while executing a network request (e.g. 400s, 500s, SSL errors and more - see [here](https://www.rubydoc.info/github/lostisland/faraday/Faraday/Error) for a complete list of subclasses of `Faraday::Error` and what can cause them).
+
+If you would like to disable this functionality, you can set `log_errors` to `false` when configuring the client:
+
+```ruby
+  client = OpenAI::Client.new(log_errors: false)
+```
+
+##### Faraday middleware
 
 You can pass [Faraday middleware](https://lostisland.github.io/faraday/#/middleware/index) to the client in a block, eg. to enable verbose logging with Ruby's [Logger](https://ruby-doc.org/3.2.2/stdlibs/logger/Logger.html):
