How to get your contributions merged smoothly and quickly.
- Create **small PRs** that are narrowly focused on **addressing a single concern**. We often times receive PRs that are trying to fix several things at a time, but only one fix is considered acceptable, nothing gets merged and both author's & review's time is wasted. Create more PRs to address different concerns and everyone will be happy.

- For speculative changes, consider opening an issue and discussing it first. If you are suggesting a behavioral or API change, consider starting with a [gRFC proposal](https://github.com/grpc/proposal).
- The grpc package should only depend on standard Go packages and a small number
of exceptions. If your contribution introduces new dependencies which are NOT
in the [list](https://godoc.org/google.golang.org/grpc?imports), you need a
discussion with gRPC-Go authors and consultants.

- Provide a good **PR description** as a record of **what** change is being made

want to fix formatting or style, do that in a separate PR.
- Maintain **clean commit history** and use **meaningful commit messages**. PRs with messy commit history are difficult to review and won't be merged.

To install this package, you need to install Go and setup your Go workspace on
your computer. The simplest way to install the library is to run:
```
$ go get -u google.golang.org/grpc
```
With Go module support (Go 1.11+), simply `import "google.golang.org/grpc"` in
your source code and `go [build|run|test]` will automatically download the
necessary dependencies ([Go modules
ref](https://github.com/golang/go/wiki/Modules)).
If you are trying to access grpc-go from within China, please see the
[FAQ](#FAQ) below.
Prerequisites
-------------
This requires Go 1.6 or later. Go 1.7 will be required soon.
Constraints
-----------
The grpc package should only depend on standard Go packages and a small number of exceptions. If your contribution introduces new dependencies which are NOT in the [list](http://godoc.org/google.golang.org/grpc?imports), you need a discussion with gRPC-Go authors and consultants.
gRPC-Go requires Go 1.9 or later.

FAQ
---
#### I/O Timeout Errors
The `golang.org` domain may be blocked from some countries. `go get` usually
produces an error like the following when this happens:
```
$ go get -u google.golang.org/grpc
package google.golang.org/grpc: unrecognized import path "google.golang.org/grpc" (https fetch: Get https://google.golang.org/grpc?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)
```
To build Go code, there are several options:
- Set up a VPN and access google.golang.org through that.
- Without Go module support: `git clone` the repo manually:
```
git clone https://github.com/grpc/grpc-go.git $GOPATH/src/google.golang.org/grpc
```
You will need to do the same for all of grpc's dependencies in `golang.org`,
e.g. `golang.org/x/net`.
- With Go module support: it is possible to use the `replace` feature of `go
mod` to create aliases for golang.org packages. In your project's directory:
```
go mod edit -replace=google.golang.org/grpc=github.com/grpc/grpc-go@latest
go mod tidy
go mod vendor
go build -mod=vendor
```
Again, this will need to be done for all transitive dependencies hosted on
golang.org as well. Please refer to [this
issue](https://github.com/golang/go/issues/28652) in the golang repo regarding
this concern.
#### Compiling error, undefined: grpc.SupportPackageIsVersion
Please update proto package, gRPC package and rebuild the proto files:
- `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}`
- `go get -u google.golang.org/grpc`
- `protoc --go_out=plugins=grpc:. *.proto`
#### How to turn on logging
The default logger is controlled by the environment variables. Turn everything
on by setting:
```
GRPC_GO_LOG_VERBOSITY_LEVEL=99 GRPC_GO_LOG_SEVERITY_LEVEL=info
```
#### The RPC failed with error `"code = Unavailable desc = transport is closing"`
This error means the connection the RPC is using was closed, and there are many
possible reasons, including:
1. mis-configured transport credentials, connection failed on handshaking
1. bytes disrupted, possibly by a proxy in between
1. server shutdown
It can be tricky to debug this because the error happens on the client side but
the root cause of the connection being closed is on the server side. Turn on
logging on __both client and server__, and see if there are any transport
errors.
