This library is intended to provide a simple interface for orchestrating relational workflows under MPC. It is mainly a reimplementation of the conclave system, with an emphasis on extensibility and the capability to interpret and compute over data that has already been secret shared.

Since most technical and architectural questions about the system are already addressed in the paper, this guide will focus mainly on using the library.
