+The static and dynamic LZ4 libraries
+====================================
+
+#### The package content
+
+- `dll\liblz4.dll` : The DLL of LZ4 library
+- `dll\liblz4.lib` : The import library of LZ4 library
+- `include\` :       Header files required with LZ4 library
+- `fullbench\` :     The example of usage of LZ4 library
+- `static\liblz4_static.lib` : The static LZ4 library
+
+
+#### The example of usage of static and dynamic LZ4 libraries with gcc/MinGW
+
+Use `make` to build `fullbench-dll` and `fullbench-lib`.
+`fullbench-dll` uses a dynamic LZ4 library from the `dll` directory.
+`fullbench-lib` uses a static LZ4 library from the `lib` directory.
+
+
+#### Using LZ4 DLL with gcc/MinGW
+
+The header files from `include\` and the import library `dll\liblz4.lib`
+are required to compile a project using gcc/MinGW.
+The import library has to be added to linking options.
+It means that if a project that uses LZ4 consists of a single `test-dll.c`
+file it should be compiled with "liblz4.lib". For example:
+```
+    gcc $(CFLAGS) -Iinclude/ test-dll.c -o test-dll dll\liblz4.lib
+```
+The compiled executable will require LZ4 DLL which is available at `dll\liblz4.dll`.
+
+
+#### The example of usage of static and dynamic LZ4 libraries with Visual C++
+
+Open `fullbench\fullbench-dll.sln` to compile `fullbench-dll` that uses a
+dynamic LZ4 library from the `dll` directory.
+
+
+#### Using LZ4 DLL with Visual C++
+
+The header files from `include\` and the import library `dll\liblz4.lib`
+are required to compile a project using Visual C++.
+1. The header files should be added to a given project or referenced within
+   `Additional Include Directories` that can be found in project properties
+   `C/C++` then `General`.
+2. The import library has to be added to `Additional Dependencies` that can
+   be found in project properties `Linker` then `Input`.
+   If one will provide only the name `liblz4.lib` without a full path to the library
+   the directory has to be added to `Linker\General\Additional Library Directories`.
+The compiled executable will require LZ4 DLL which is available at `dll\liblz4.dll`.
