+# ESP-IDF
+
+ESP-IDF is planned for later stages.
+
+## Use Later For
+
+- Deeper ESP32 architecture.
+- Tasks, timers and FreeRTOS concepts.
+- More production-like firmware structure.
+- Wi-Fi reliability and power management.
+
+## Current Decision
+
+Do not start here. First build confidence with safety, measurements, GPIO, PWM and I2C using Arduino Core or PlatformIO.
