 **Architecture overview**: This reference application is cross-platform either at the server and client side, thanks to .NET Core services capable of running on Linux or Windows containers depending on your Docker host, and to Xamarin for mobile apps running on Android, iOS or Windows/UWP plus any browser for the client web apps. 
 The architecture proposes a simplified microservice oriented architecture implementation with multiple autonomous microservices (each one owning its own data/db) and implementing different approaches within each microservice (simple CRUD vs. DDD/CQRS patterns) using Http as the current communication protocol. 
 <p>
-The plan is to add asynchronous communication for data updates propagation across multiple services based on integration events and an event bus plus other features defined at the <a href='https://github.com/dotnet/eShopOnContainers/wiki/01.-Roadmap-and-Milestones-for-future-releases'>roadmap</a>.

 Additional miroservice styles with other frameworks and No-SQL databases will be added, eventually.

 ## Related documentation and guidance
 While developing this reference application, we are creating a reference Guide/eBook named <b>"Architecting and Developing Containerized and Microservice based .NET Applications"</b> which explains in detail how to develop this kind of architectural style (microservices, Docker containers, Domain-Driven Design for certain microservices) plus other simpler architectural styles, like monolithic apps that can also live as Docker containers.
 <p>
-There's also an additional eBook focusing on Containers/Docker lifecycle (DevOps, CI/CD, etc.) with Microsoft Tools, already published.
