+## Acknowledgement
+
+```plaintext
+LZMA SDK is placed in the public domain.
+
+Anyone is free to copy, modify, publish, use, compile, sell, or distribute the original LZMA SDK code, either in source code form or as a compiled binary, for any purpose, commercial or non-commercial, and by any means.
+
+Note: The abbreviation LZMA originally stood for Lempel - Ziv - Markov chain - Arithmetic coding. Preliminary versions of LZMA used arithmetic coding. But in the final version of LZMA, arithmetic coding was replaced by range coding.
