+Overview
+--------
+
+Remote Procedure Calls (RPCs) provide a useful abstraction for building 
+distributed applications and services. The libraries in this repository
+provide a concrete implementation of the gRPC protocol, layered over HTTP/2.
+These libraries enable communication between clients and servers using any
+combination of the supported languages.

 provide a concrete implementation of the gRPC protocol, layered over HTTP/2.
 These libraries enable communication between clients and servers using any
 combination of the supported languages. 
+
+Developers using gRPC typically start with the description of an RPC service
+(a collection of methods), and generate client and server side interfaces
+which they use on the client-side and implement on the server side.
+
+Protocol
+--------
+
+The gRPC protocol specifies the abstract requirements for communication between
+clients and servers. A concrete embedding over HTTP/2 completes the picture by
+fleshing out the details of each of the required operations.

 These libraries enable communication between clients and servers using any
 combination of the supported languages. 
 
+
+##Interface
+
+
 Developers using gRPC typically start with the description of an RPC service
 (a collection of methods), and generate client and server side interfaces
 which they use on the client-side and implement on the server side.
 
-Protocol
---------
+By default, gRPC uses [Protocol Buffers](github.com/google/protobuf) as the
+Interface Definition Language (IDL) for describing both the service interface
+and the structure of the payload messages. It is possible to use other 
+alternatives if desired.
+
+###Surface API
+Starting from an interface definition in a .proto file, gRPC provides
+Protocol Compiler plugins that generate Client- and Server-side APIs. 
+gRPC users typically call into these APIs on the Client side and implement
+the corresponding API on the server side.
+
+#### Synchronous vs. Async
+Synchronous RPC calls, that block till a response arrives from the server, are
+the closest approximation to the abstraction of a procedure call that RPC
+aspires to.
+
+On the other hand, networks are inherently asynchronous and in many scenarios,  
+it is desirable to have the ability to start RPCs without blocking the current
+thread. 
+
+The gRPC programming surface in most languages comes in both Synchronous and
+async flavors.
+
+
+## Streaming
+
+gRPC supports streaming semantics, where either the client or the server (or both)
+send a stream of messages on a single RPC call. The most general case is 
+Bidirectional Streaming where a single gRPC call establishes a stream where both 
+the client and the server can send a stream of messages to each other. The streamed
+messages are delivered in the order they were sent.
+
+
+
+
+
+#Protocol
 
 The gRPC protocol specifies the abstract requirements for communication between
 clients and servers. A concrete embedding over HTTP/2 completes the picture by
 fleshing out the details of each of the required operations.
 
+## Abstract gRPC protocol
+A gRPC RPC comprises of a bidirectional stream of messages, initiated by the client. In the client-to-server direction, this stream begins with a mandatory 'Call Header', followed by optional `Initial-Metadata`, followed by zero or more `Payload Messages`. The server-to-client direction contains an optional `Initial-Metadata`, followed by zero or more `Payload Messages` terminated with a mandatory `Status` and optional `Status-Metadata` (a.k.a.,`Trailing-Metadata').

 ## Abstract gRPC protocol
-A gRPC RPC comprises of a bidirectional stream of messages, initiated by the client. In the client-to-server direction, this stream begins with a mandatory 'Call Header', followed by optional `Initial-Metadata`, followed by zero or more `Payload Messages`. The server-to-client direction contains an optional `Initial-Metadata`, followed by zero or more `Payload Messages` terminated with a mandatory `Status` and optional `Status-Metadata` (a.k.a.,`Trailing-Metadata').

+## Implementation over HTTP/2
+The abstract protocol defined above is implemented over [HTTP/2](https://http2.github.io/). gRPC bidirectional streams are mapped to HTTP/2 streams. The contents of `Call Header` and `Initial Metadata` are sent as HTTP/2 headers and subject to HPAC compression. `Payload Messages` are serialized into a byte stream of length prefixed gRPC frames which are then fragmented into HTTP/2 frames at the sender and reassembled at the receiver. `Status` and `Trailing-Metadata` are sent as HTTP/2 trailing headers (a.k.a., trailers).
