+
+## How is Akka.NET Used?
+
+Akka.NET can be used in-process or inside large, distributed real-time systems; we support a wide variety of use cases.
+
+Akka.NET can be used to solve the following types of problems:
+
+1. **Concurrency** - Akka.NET actors only process messages one-at-a-time and they do so in first in, first out (FIFO) order; this means that any application state internal to an actor is automatically thread-safe without having to use `lock`s or any other shared-memory synchronization mechanisms.
+2. **Stream Processing** - Akka.NET actors and [Akka.Streams](https://getakka.net/articles/streams/introduction.html) make it easy to build streaming applications, used for processing incoming streams of data or incoming streams of live events such as UI or network events inside native applications.
+3. **Event-Driven Programming** - actors make it easy to build event-driven applications, as actors' message-processing routines naturally express these types of designs.
+4. **Event Sourcing and CQRS** - [Akka.Persistence](https://getakka.net/articles/persistence/architecture.html), used by actors to make their state re-entrant and recoverable across restarts or migrations between nodes, natively supports event sourcing. [Akka.Persistence.Query](https://getakka.net/articles/persistence/persistence-query.html) can be used to compute CQRS-style projections and materialized views from Akka.Persistence data.
+5. **Location Transparency** - [Akka.Remote](https://getakka.net/articles/remoting/index.html) makes it simple for actors in remote processes to transparently communicate with each other.
+6. **Highly Available, Fault-Tolerant Distributed Systems** - [Akka.Cluster](https://getakka.net/articles/clustering/cluster-overview.html), [Akka.Cluster.Sharding](https://getakka.net/articles/clustering/cluster-sharding.html), and other tools built on top of Akka.Cluster make it possible to build highly available and fault-tolerant distributed systems by leveraging peer-to-peer programming models with topology-aware message routing and distribution.
+7. **Low Latency, High Throughput** - Akka.NET aims to be low latency and high throughput, processing 10s millions of messages per second in-memory and hundreds of thousands of messages per second over remote connections.
+
+## Where Can I Learn Akka.NET?

+You can start by taking the [Akka.NET Bootcamp](https://learnakka.net/), but there are many other great [learning resources for Akka.NET Online](https://getakka.net/community/online-resources.html).
