+Zstandard library : usage examples
+==================================
+
+- [Simple compression](simple_compression.c) :
+  Compress a single file.
+  Introduces usage of : `ZSTD_compress()`
+
+- [Simple decompression](simple_decompression.c) :
+  Decompress a single file.
+  Only compatible with simple compression.
+  Result remains in memory.
+  Introduces usage of : `ZSTD_decompress()`
+
+- [Streaming memory usage](streaming_memory_usage.c) :
+  Provides amount of memory used by streaming context
+  Introduces usage of : `ZSTD_sizeof_CStream()`
+
+- [Streaming compression](streaming_compression.c) :
+  Compress a single file.
+  Introduces usage of : `ZSTD_compressStream()`
+
+- [Multiple Streaming compression](multiple_streaming_compression.c) :
+  Compress multiple files in a single command line.
+  Introduces memory usage preservation technique,
+  reducing impact of malloc()/free() and memset() by re-using existing resources.
+
+- [Streaming decompression](streaming_decompression.c) :
+  Decompress a single file compressed by zstd.
+  Compatible with both simple and streaming compression.
+  Result is sent to stdout.
+  Introduces usage of : `ZSTD_decompressStream()`
+
+- [Dictionary compression](dictionary_compression.c) :
+  Compress multiple files using the same dictionary.
+  Introduces usage of : `ZSTD_createCDict()` and `ZSTD_compress_usingCDict()`
+
+- [Dictionary decompression](dictionary_decompression.c) :
+  Decompress multiple files using the same dictionary.
+  Result remains in memory.
+  Introduces usage of : `ZSTD_createDDict()` and `ZSTD_decompress_usingDDict()`
