+# MinLZ 
+
+I have taken the experiences from this library and created a backwards compatible compression package called MinLZ.
+
+That package will seamlessly decode S2 content, making the transition from this package fairly trivial.
+
+There are many improvements to pretty much all aspects of S2 since we have "broken free" of the Snappy format specification.
+You can read a writeup on [Design and Improvements over S2](https://gist.github.com/klauspost/a25b66198cdbdf7b5b224f670c894ed5).
+
+The only aspect not covered is custom dictionary encoding. While I do intend to fix errors in this package, 
+I do not expect to make significant improvements, since I consider MinLZ a better basis for going forward.
+
+See https://github.com/minio/minlz for all details. 
+
 # S2 Compression
 
 S2 is an extension of [Snappy](https://github.com/google/snappy).
