-The main goal of the lwext4 project is to provide ext2/3/4 filesystem
-library for microcontrolers with SD/MMC card support. 
+The main goal of the lwext4 project is to provide ext2/3/4 filesystem for microcontrollers. It may be an interesting alternative for traditional MCU filesystem libraries (mostly based on FAT32).
 
+Lwext4 may be used with SD/MMC card, USB flash drive or other block based memory device. However it is not good for flash memory–based storage devices.
+
+Code is also available on github:
