+Zstandard library : usage examples
+==================================
+
+- [Dictionary decompression](dictionary_decompression.c)
+  Decompress multiple files using the same dictionary.
+  Compatible with Legacy modes.
+  Introduces usage of : `ZSTD_createDDict()` and `ZSTD_decompress_usingDDict()`
