+		erofs-utils
+		===========
+		erofs-utils includes user-space tools for erofs filesystem images.
+		Currently only mkfs.erofs is available.
+		
+		Mkfs.erofs
+		----------
+		It can create 2 primary kinds of erofs images: (un)compressed.
+		- For compressed images, it's able to use several compression algorithms, but lz4(hc) are only supported due to the current linux kernel implementation.
+		- For uncompressed images, it can decide whether the last page of a file should be inlined or not properly [1].
+		How to generate erofs images
+		~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+		Currently lz4 and lz4hc are available for compression, e.g.
+		$ mkfs.erofs -zlz4hc foo.erofs.img foo/
+		Or leave all files uncompressed as a option:
+		$ mkfs.erofs foo.erofs.img foo/
+		
+		Known issues
+		~~~~~~~~~~~~
+		1. LZ4HC cannot compress long zeroed buffer properly with
+		LZ4_compress_HC_destSize()
+		https://github.com/lz4/lz4/issues/784
