 - Custom PWM: If Sming is compiled with ENABLE_CUSTOM_PWM=1 then instead of using the Espressif SDK pwm library
 a [custom PWM library](https://github.com/StefanBruens/ESP8266_new_pwm) will be used.
 - SSL: The SSL support is not built-in by default to conserve resources. If you want to enable it then take a look at the [Readme](https://github.com/SmingHub/Sming/blob/develop/samples/Basic_Ssl/README.md) in the Basic_Ssl samples.
+- Custom Heap Allocation: If your application is experiencing heap fragmentation then you can try the Umm Malloc heap allocation. To enable it compile
+Sming with ENABLE_CUSTOM_HEAP=1. In order to use it in your sample/application make sure to compile the sample with ENABLE_CUSTOM_HEAP=1. Avoid enabling
+your custom heap allocation AND -mforce-l32 compiler flag.
 
 
 You can find more information about compilation and flashing process by reading esp8266.com forum discussion thread.
