+#### Proxy support
+
+You can use proxy with Faraday
+
+```ruby
+proxy = {
+  :uri      => 'http://proxy.example.com',
+  :user     => 'foo',
+  :password => 'bar'
+}
+
+OpenAI::Client.new(access_token: "access_token_goes_here", proxy: proxy)
+```
+
+Or use with string
+
+```ruby
+OpenAI::Client.new(access_token: "access_token_goes_here", proxy: "foo:bar@http://proxy.example.com")
+```
