+================================================================================
+
+Overview:
+
+The TinyCrypt Library provides an implementation for constrained devices of a
+minimal set of standard cryptography primitives.
+
+This is a modified form of the library based on version 0.2.8. included as part
+of Mbed TLS as a compilation option. It is not included in it's full form and
+those wishing to use TinyCrypt should use the original unmodified project.
+
+The original project, can be found here: https://github.com/intel/tinycrypt
+
+Contributions should be made upstream to that project, and full documentation
+can be found in the originating repository.
+
+================================================================================
+
+Organization:
+
+tinycrypt: C source code of the cryptographic primitives.
+include/tinycrypt: C header files of the cryptographic primitives.
+
+No documentation is provided, and instead is available with the original
+project.
+
+Tests are provided as part of Mbed TLS and the Mbed TLS test suites.
+
+================================================================================
+
+Building:
+
+To include TinyCrypt as part of Mbed TLS, enable the configuration option
+MBEDTLS_USE_TINYCRYPT in the configration file 'include/mbedtls/config.h', and
+build as Mbed TLS as normal.
