-        Over 16 MBytes space on flash mentioned above can be only used for ``data saving``, like file system.
+        The part of flash above 16 MB can be used for data storage, for example using a file system.
 
         Mapping data/instructions to 32-bit physical address space (so as to be accessed by the CPU) needs the support of MMU. However {IDF_TARGET_NAME} doesn't support this feature. Only ESP32-S3 and ESP32-P4 supports this up to now.

+    For Quad flash chips, by default, the part of flash above 16 MB can be used for data storage, for example using a file system.
 
-    Furthermore, to map data/instructions to 32-bit physical address space (so as to be accessed by the CPU), please enable the config ``IDF_EXPERIMENTAL_FEATURES`` and ``BOOTLOADER_CACHE_32BIT_ADDR_QUAD_FLASH``.
+    *Experimental Feature*: To enable full support for Quad flash addresses above 16MB (for both code execution and data access), enable this experimental feature by setting below options to ``y``:
+    - :ref:`CONFIG_IDF_EXPERIMENTAL_FEATURES`
+    - :ref:`CONFIG_BOOTLOADER_CACHE_32BIT_ADDR_QUAD_FLASH`
 
-    Please note that, this option is experimental, which means it can not be used on all flash chips stably. For more information, please contact Espressif Business Support.
