 #### Minimal library files
 
-##### Shared ressources
+To build the zstd library the following files are required:
 
-- [mem.h](mem.h)
+- [common/bitstream.h](common/bitstream.h)
-- [error_private.h](error_private.h)
+- [common/error_private.h](common/error_private.h)
-- [error_public.h](error_public.h)

+- compress/zstd_opt.h 
+- decompress/fse_decompress.c

+- decompress/zstd_decompress.c
 
 Stable API is exposed in [zstd.h].
 Advanced and experimental API is exposed in `zstd_static.h`.
 `zstd_static.h` API elements should be used with static linking only,
 as their definition may change in future version of the library.

+#### Separate compressor and decompressor
+
+To build a separate zstd compressor all files from common/ and compressor/ directories are required.
+In similar way to build a separate zstd decompressor all files from common/ and decompressor/ directories are needed.

 #### Buffered streaming
 
 This complementary API makes streaming integration easier.
 It is used by `zstd` command line utility, and [7zip plugin](http://mcmilk.de/projects/7-Zip-ZStd) :
 
-- zbuff.c
+- common/zbuff.h
-- zbuff.h
+- common/zbuff_static.h
-- zbuff_static.h
+- compress/zbuff_compress.c
+- decompress/zbuff_decompress.c
 
 #### Dictionary builder
 
 To create dictionaries from training sets :
 
-- divsufsort.c
+- dictBuilder/divsufsort.c
-- divsufsort.h
+- dictBuilder/divsufsort.h
-- zdict.c
+- dictBuilder/zdict.c
-- zdict.h
