This tutorial walks through how I installed Go, and how I got started with it. I will keep on updating it, through my journey of learning Go.

Installation

Retrieve the tarball using curl by the following command:

 curl -O https://storage.googleapis.com/golang/go1.6.linux-amd64.tar.gz

Next, use tar to extract the tarball : (Here x tells it to extract, v denotes verbose output and f denotes that we are mentioning a file name.)
```
 tar xvf go1.6.linux-amd64.tar.gz
```
This creates a directory go in the home directory. We recursively change Go’s owner and group to root and move it to usr/local :
```
 sudo chown -R root:root ./go
 sudo mv go /usr/local
```
(usr/local/go is the offical recommended location.)
Setting up paths :

At the end of the file ~/.profile, add the following lines:
```
 export GOPATH=$HOME/work/go
 export PATH=$PATH:/usr/local/bin:$GOPATH/bin
```
GOPATH contains the path of the folder where you will write all your Go programs. After saving the file, refresh it by doing:
```
 source ~/.profile
```

This completes our installation process.

Writing “Hello World” program

Create a working directory (which you added in the .profile as GOPATH) :
```
 mkdir -p work/go/src/hello
```

Create a simple Hello world file inside the above dir:

 nano ~/work/go/src/hello/hello.go

Inside the editor, paste the code below:

 package main

 import "fmt"

 func main() {
     fmt.Printf("hello, world\n")
 }

Compile the above code using install command:
```
 go install work/go/src/hello
```
This will create a binary in the dir work/go/bin
Execute this by just typing
```
 hello
```
since it is already added in the path.
