+ESP RainMaker Programming Guide
+===============================
+ESP RainMaker is an end-to-end solution offered by Espressif to enable remote control and monitoring for products based on ESP32 series of SoCs (e.g., ESP32, ESP32-S2, ESP32-C3, ESP32-C6, ESP32-C2, etc.) without any configuration required in the Cloud. It provides a device SDK, self-adapting phone apps, transparent cloud middleware and host utilities to reduce complexity in development of connected devices.
