+
+Introduction
+------------
+
+OpenAES is an open source implementation of the Advanced Encryption
+Standard.  It is distributed as a portable, lightweight C library that can
+be easily integrated into applications.
+
+Compiling
+---------
+
+OpenAES has been tested with the GCC as well as VC compilers.  It is
+necessary to compile the source files located in ./src, and to add ./inc to
+the include paths.
+
+If you are building with OAES_HAVE_ISAAC defined (true by default), then
+you also need to link in the source files under ./src/isaac and also add
+./src/isaac to the include paths.
+
+You may edit ./inc/oaes_config.h to modify build options.
+
+CMake 2.8.0 can be used to build the test programs on different platforms.
+
+In a Linux command line terminal type:
+
+cmake .
+make
+
+In Windows, in a Visual Studio command line window type:
+
+cmake . -G "NMake Makefiles"
+nmake
+
+Usage
+-----
+
+oaes_lib usage is described in the header file ./inc/oaes_lib.h.
+
+The oaes command line application help manual can be obtained by using the
+--help command line options.
+
+The oaes_setup Windows installer integrates with the Windows shell.  It can be
+used by right clicking a file in Windows Explorer and then selecting a
+subcommand from the OpenAES menu.
+
+Samples
+-------
+
+Samples applications are provided in the /test folder.
