  * U8g2 RSS Reader
  * This is a simple RSS Reader sample with UTF-8 support
  *
+ *  * Raspberry Pi Pico W dependent libraries:
+ * HttpClient: https://github.com/moononournation/HttpClient.git
+ *
  * Setup steps:
  * 1. Fill your own SSID_NAME, SSID_PASSWORD, RSS_HOST, RSS_PORT, RSS_PATH
  * 2. Change your LCD parameters in Arduino_GFX setting
