## Overview

The **Infrastructure Library** contains ***the current state* of our thinking about the problems we are solving**. This happens through two stages:

- First, we begin with **blueprints**, which define and scope a problem and provide options on how we might approach said problem.
- Second is the **design** stage, which fleshes out the approach and provides the technical design on the solution.

Once we have executed on the design, we update the relevant **architectural** and/or **operational** documentation. See the [Library Workflow](./workflow/) for more details.
