How to move the index.html from root content to other file in page folder?

[XieSandi]

Hey there, thanks for making such an amazing Jekyll theme/template.

So, I trying to make a custom home page/index page. but I want to migrate the current index page as blog page
The structure will be :
Home (my custom page)
├── About
├── Blog (the previous index.html content move into here)
└── Contact

I'm trying to copy this code from the default index into the blog page (change the title inside the code too)

---
layout: default
title: Home
---

<!-- Posts Index
================================================== -->
<div class="blog-grid-container">
    {% for post in paginator.posts %}
        {% include postbox.html %}
    {% endfor %}
</div>

<!-- Pagination
================================================== -->
<div class="bottompagination">
<span class="navigation" role="navigation">
    {% include pagination.html %}
</span>
</div>

But the blog page is blank, there is no rendered content.

Sorry for the silly question, but I'm new to Jekyll.

Thanks in advance!
