#If you are in a hurry

For language-specific installation instructions for gRPC runtime, please
refer to these documents

 * [C++](examples/cpp): Currently to install gRPC for C++, you need to build from source as described below.
 * [C#](src/csharp): NuGet package `Grpc`
 * [Go](https://github.com/grpc/grpc-go): `go get google.golang.org/grpc`
 * [Java](https://github.com/grpc/grpc-java)
 * [Node](src/node): `npm install grpc`
 * [Objective-C](src/objective-c)
 * [PHP](src/php): `pecl install grpc-beta`
 * [Python](src/python/grpcio): `pip install grpcio`
 * [Ruby](src/ruby): `gem install grpc`


#Pre-requisites

##Linux

```sh
 $ [sudo] apt-get install build-essential autoconf libtool
```

##Mac OSX

For a Mac system, git is not available by default. You will first need to
install Xcode from the Mac AppStore and then run the following command from a
terminal:

```sh
 $ [sudo] xcode-select --install
```

##Protoc

By default gRPC uses [protocol buffers](https://github.com/google/protobuf),
you will need the `protoc` compiler to generate stub server and client code.

If you compile gRPC from source, as described below, the Makefile will
automatically try and compile the `protoc` in third_party if you cloned the
repository recursively and it detects that you don't already have it
installed.


#Build from Source

For developers who are interested to contribute, here is how to compile the
gRPC C Core library.

```sh
 $ git clone https://github.com/grpc/grpc.git
 $ cd grpc
 $ git submodule update --init
 $ make
 $ [sudo] make install
```
