Let's break down the block of code above. We import the `net/http` package: this package contains the web server itself, if you continue with Go as a web development language, be prepared to use this package often. Then we also import the `io` package, we will make use of this later to actually serve something to the client. Let's break down the block of code above.

In the `main` function(denoted by `package main`) we do two things. First we instruct our server to let the function called `servePage` handle all incoming traffic to `/` - in this case it means that it handles requests to *any* `URL` path. The second thing we do is actually activating the server. We do this using a function named `ListenAndServe`. This function requires two parameters: the `port` (as a `string` data type), in this case it's `8080`, and the `handler` (as `Handler`) - however the last one isn't important yet. We will just make it `nil` and everything will work just fine. If you'd like to read more about http handlers in go I recommend referring to the official documentation of the `net/http` package found here: https://golang.org/pkg/net/http/.

In the `servePage` we do just one simple thing, for now. Using the `io` package and the `WriteString` function that it contains we can respond to the clients' request with the text `Hello world!` (or any string you choose, of course). You also might have noticed that the `servePage` function has two arguments: the `writer` and the `request`. With the writer you can actually respond to a `HTTP` request and with the `request` you may get more information about the request itself. In the `servePage` we do just one simple thing, for now.
