Golang (or Go, they are interchangeable and I will use it as such) has blown up over the recent years. For example, some features piqued my interest and when say piqued, I mean it. You probably aren't as hyped about Golang as I am. I suppose it helps when you are such a nerd about back-end and server development as well.

I'm back! A lot to take in, isn't there? I'm a beginner too so I will try my best to explain this to my utmost competency. I'm back! A lot to take in, isn't there? I'm a beginner too so I will try my best to explain this to my utmost competency.
So the the `package main` deal up top. You will need that to package that up if you want to share this awesome hello world app with your friends. So the the `package main` deal up top. You will need that to package that up if you want to share this awesome hello world app with your friends.
The `import` keyword imports packages to help with Go development. So, in this case, I'm importing the formatting tool, `"fmt"`, and the operating system tool, `"os"`, into my awesome hello world app which both packages are in the standard library. With that said, you could import other third party packages, like the ssh package. Since you can't find it [here](https://golang.org/pkg/), I looked on Golang's third party packages for ssh packages and it was pretty obvious that I'd find one.

I think that's pretty neat as you have flexible package management built right in to Go. I think that's pretty neat as you have flexible package management built right in to Go.
Next up, variables! Variables are a bit different as you have to declare them with a `var` and then the name of the variable and then the type of the variable. In my case, I need a variable called `name` with the `string` type because I know it's going to be `string` to begin with. Since Go is statically typed, this kind of breaks the rules (kind of like C# with the `var` keyword) but Go is super smart and can infer the type for you by using the `:=` operator.

Depending on what the argument is when the hello world app runs, it will infer the type for you. Depending on what the argument is when the hello world app runs, it will infer the type for you.
