used TDD to create resources to view in index

Indent between the `do..end` blocks. You probably want some additional HTML to markup the content on this page. Although it passes the tests, it's not very descriptive.

```HTML+ERB
<h1>Resources</h1>

<% @resources.each do |resource| %>
  <h2><%= link_to resource.title, resource.url %></h2>
  <p><%= resource.description %></p>
<% end %>
```
