+                Amazon has released an SMP version of the FreeRTOS Kernel which can be found via the following link:
+                https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/smp
+
+                IDF has added an experimental port of this SMP kernel located in
+                components/freertos/FreeRTOS-Kernel-SMP. Enabling this option will cause IDF to use the Amazon SMP
+                kernel. Note that THIS FEATURE IS UNDER ACTIVE DEVELOPMENT, users use this at their own risk.

+                Leaving this option disabled will mean the IDF FreeRTOS kernel is used instead, which is located in:
+                components/freertos/FreeRTOS-Kernel. Both kernel versions are SMP capable, but differ in
+                their implementation and features.
