-# lz4
-LZ4 compression and decompression in pure Go.
-
-## Usage
-
-```go
-import "github.com/pierrec/lz4"
-```
-
-## 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.
-
-For a complete description of an lz4 compressed block, see:
-http://fastcompression.blogspot.fr/2011/05/lz4-explained.html
-
-See https://github.com/Cyan4973/lz4 for the reference C implementation.
