Need more instructions for inital setup for those less familiar with Go

First of all, thank you very much for providing this. It works like a dream. However, I stumbled a bit on setting up my initial environment given that I had never worked with Go before. At the very least, a link to Go installation instructions and the command to get all dependencies for a Go project would be helpful. Below is the verbose set of commands that worked for me.

wget https://dl.google.com/go/go1.9.2.linux-amd64.tar.gz
sudo tar -C /usr/local -xvf go1.9.2.linux-amd64.tar.gz
export GOROOT=/usr/local/go
export PATH=$PATH:$GOROOT/bin

# Set path for go
mkdir $HOME/go
export GOPATH="$HOME/go"
cd $HOME/go

# Git clone s3-sync
git clone https://github.com/checkr/s3-sync.git
cd s3-sync/

# Get all dependencies
go get ./...

# Now edit $HOME/go/s3-sync/config.prod.yaml, ex
cp $HOME/go/s3-sync/config.yaml $HOME/go/s3-sync/config.prod.yaml
vim $HOME/go/s3-sync/config.prod.yaml

# Now you can run the program
go run main.go sync --config config.prod.yaml

Alternatively, it could also be helpful to provide some binary releases, so that users don't have to build the application themselves.
