<h2>Overview</h2>
<p>Rails Event Store (RES) is a versatile library designed for publishing, consuming, storing, and retrieving events. It serves as a valuable tool for implementing an event-driven architecture in your Rails application. With RES, you can decouple core business logic, create communication layers between components, react to events synchronously or asynchronously, extract side-effects from controllers and services, build audit logs, create read models, and implement event sourcing.</p>
