+// * For no-proxy testing need to run the tests with direct connection to the internet
+// * List of free proxies for testing can be found at https://proxy-list.org/english/index.php
+//   Example: #define HTTP_PROXY "http://162.223.90.130:80"
 #define HTTP_PROXY "51.159.4.98:80"
 #define HTTPS_PROXY "51.104.53.182:8000"
