The format itself is documented (https://github.com/facebook/zstd/blob/master/zstd_compression_format.md https://github.com/facebook/zstd/blob/master/zstd_compressio...) with the intention of other implementations and language bindings being readily available. We also have a zlib-compatible API for easier porting to applications already using Zlib. Our hope is that Zstandard is both easy to use and easy to contribute to.
