-.. envvar:: ENABLE_MALLOC_COUNT
-
-   We require :component:`malloc_count` to keep track of heap usage for system_get_free_heap_size().
-   It does this by hooking the memory allocation routines (malloc, free, etc.).
-   If you wish to disable this behaviour, set `ENABLE_MALLOC_COUNT=0`.
-   If using tools such as `Valgrind <https://www.valgrind.org>`__, this will provide a cleaner trace.
+This Component supplments the actual heap implementation provided by the ESP IDF SDK.
