+## Installation
+
+Just copy the contents of the include folder in your project with `msgpack_describe.h` as an optional header.
+
+## Dependencies
+
+You just need a C++17 compiler. If you want to avail yourself of the convenient Boost.Describe integration in `msgpack_describe.h`, then you'll require that Boost library.
