The Open Roles project is a new project that puts enterprise level role management on the blockchain. The task is to create a picture based off of the existing design data and a chat with the project that describes how Open Roles works for smart contracts on the Ethereum Blockchain

Start by locating the existing design data and the chat referenced in the issue, then review how Open Roles works for smart contracts on Ethereum. The work is done when a clear diagram explains the project's role-management flow based on those sources.
