+
+==About==
+
+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:
+https://github.com/gkostka/lwext4
+
+Feel free to contact me:
+kostka.grzegorz@gmail.com
+
+==Credits==
+
+The most of the source code of lwext4 was taken from HelenOS:
+* http://helenos.org/
+Some features are based on FreeBSD and Linux implementations.
+
+KaHo Ng (https://github.com/ngkaho1234):
+* advanced extents implementation
+* xattr support
+* metadata checksum suport
+* many bugfixes & improvements
