title: How can I get a post excerpt in Jekyll?
body: <p>I'm creating a new blog using <a href="https://jekyllrb.com" rel="noreferrer">Jekyll</a>.</p>
  
  <p>On the main page, there will be a list of my 10 most recent posts.</p>
  
  <p>The entries on this list will include a title, the post date, and an <em>excerpt</em>, most likely the first paragraph.</p>
  
  <p>I'm only familiar with using Jekyll for basic templates, so I can either put only a variable in the page, or include the entire post.</p>
  
  <p>Is there a way to somehow avoid using <code>post.content</code> in the paginator, and only include up to a certain point in the post, which I define (e.g. ``{% endexcerpt %}`?</p>
