 ## Description
 Package lz4 implements reading and writing lz4 compressed data (a frame),
 as specified in http://fastcompression.blogspot.fr/2013/04/lz4-streaming-format-final.html.
-Although the block level compression and decompression functions are exposed and are fully compatible
-with the lz4 block format definition, they are low level and should not be used directly.
+
+This package is **compatible with the LZ4 frame format** although the block level compression 
+and decompression functions are exposed and are fully compatible with the lz4 block format 
+definition, they are low level and should not be used directly.
