title: Pagination in Wagtail
body: <p>I'm fairly new to Wagtail, and I am in the process of creating a site that will have a Resources (blog) section and I'm not sure how to implement pagination so that there are only 5 posts on each page and the user has to click a number (1, 2, 3, etc.) to go to the next page to see the next 5 posts. </p>
  
  <p>I have this in my template for the pagination section of the resource/blog index page:</p>
  
  <pre><code>&lt;ul class="pagination"&gt;
    &lt;li&gt;&lt;a href="#"&gt;&lt;i class="fa fa-angle-left"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;
    &lt;li class="active"&gt;&lt;a href="#"&gt;1&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="#"&gt;2&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="#"&gt;3&lt;/a&gt;&lt;/li&gt;
    &lt;li&gt;&lt;a href="#"&gt;&lt;i class="fa fa-angle-right"&gt;&lt;/i&gt;&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>What code do I need to incorporate to make this functional? Thanks in advance.</p>
