You have two choices when it comes to managing this front page.
First create your own index page in content: hugo new ./content/index.md
Set a type in the “front matter” to index
eg:
+++
date = "2015-03-17T15:36:56Z"
draft = false
title = "index"
type = "index"
+++
## Add your markdown content to your frontpage.
Hello welcome to my driver docs
Create your own layouts\index.html
eg:
{{ partial "header.html" . }}
<h2>Add your HTML content to your frontpage.</h2>
{{ partial "footer.html" . }}
