+## What is Armeria?
+
+_Armeria_ is your go-to microservice framework for any situation. You can build any type of
+microservice leveraging your favorite technologies, including [gRPC](https://grpc.io/),
+[Thrift](https://thrift.apache.org/), [Kotlin](https://kotlinlang.org/),
+[Retrofit](https://square.github.io/retrofit/), [Reactive Streams](https://www.reactive-streams.org/),
+[Spring Boot](https://spring.io/projects/spring-boot) and [Dropwizard](https://www.dropwizard.io/).
+
+It is open-sourced by the creator of [Netty](https://netty.io/) and his colleagues at
+[LY Corporation](https://techblog.lycorp.co.jp/en).

+## Features
+
+### HTTP/2
+
+- Supports HTTP/2 on both TLS and cleartext connections
+- Supports protocol upgrade via both HTTP/2 connection preface and traditional HTTP/1 upgrade request
+- Fully compatible with existing HTTP/1 servers
+- Integrated PROXY protocol support for interoperability with load balancers such as HAProxy and AWS ELB.
+
+### Integration with gRPC and Thrift
+
+- Your gRPC or Thrift service implementation runs on top of Armeria without any modification.
+- Works with the official gRPC or Thrift-over-HTTP client
+- Works with the code generated by the official Protobuf or Thrift IDL compiler
+- Supports various protocol combinations, such as:
+  - gRPC-over-HTTP/1 & 2
+  - Thrift-over-HTTP/1 & 2
+  - gRPC-Web
+- See [Running a Thrift service](/docs/server-thrift) and [Running a gRPC service](/docs/server-grpc).
+
+### Essential features for building microservices
+
+- Metrics
+- Circuit breaker
+- Client-side health-check and load-balancing
+- Service discovery from various sources such as DNS and ZooKeeper
+  - See [Client-side load balancing and service discovery](/docs/client-service-discovery).
+- Distributed call tracing via Zipkin
+
+### Interactive web-based debug console
+
+- Browse the list of available RPC operations
+- Invoke an RPC operation via a web form
+- Share an RPC request with your colleagues so they can reproduce the problem easily
+  - Just like sharing a cURL command, but works for RPC
+- See [Browsing and invoking services with DocService](/docs/server-docservice).
+
+### Completely asynchronous and reactive
+
+- Built on top of Reactive Streams and Java 8 CompletableFuture
+- Asynchronous connection pool ensures your application never blocks even on pool exhaustion.
+- Domain name lookups are also fully asynchronous thanks to Netty’s asynchronous domain name resolver.
+
+### Compatibility with existing Java EE web applications
+
+- Runs any Java EE web applications such as Spring Boot on the same TCP/IP port
+- Your Java EE web application speaks HTTP/2!
+- See [Embedding a servlet container](/docs/server-servlet).
+
+### Even higher performance on Linux
+
+- JNI-based socket I/O
+- BoringSSL-based TLS connections
