Example of how to use Jekyll's `excerpt` tag.

excerpt.md

If your post looked something like:

# Awesome Blog Post

Here is an example post to show how to use the new `excerpt` tag.

The excerpt tag provides a quick and easy way to tease a post by exposing only the first paragraph such as on a blog index page.

Then in your template, you could create an index file like this:

<ul>
{% for post in site.posts %}
  <li>
    <a href="{% post.permalink %}">{% post.title %}</a>
    <p>{{ post.excerpt }}</p>
  </li>
{% endfor %}
</ul>

Which would produce:

• Awesome Blog Post

This didn't work for me either, I had to escape the html more comment inside the liquid expand. Then it worked.

I believe the excerpt method takes the whole first paragraph if you don't specify the separator.

Someone could say me the best excerpt_delimiter for using --- as excerpt delimiter?

I use the following

{{ post.content | strip_html | truncatewords:75 }}

Thanks @ahmadajmi
If you leave out "strip_html" a post image will show if it is before the truncate.
The following works as well.
{{ post.excerpt | strip_html | truncatewords:75 }}

I use the following

{{ post.content | strip_html | truncatewords:75 }}

Awesome. I was wondering what would happen if an image was within the post.content excerpt area. I didn't want the image displayed, but only the text. Thanks for sharing! The strip_html did the trick.

I have a one sentence paragraph, and a full paragraph below. Any way to set the excerpt to show more than one paragraph and truncate at 275?

I have specified excerpt_separator: <!--more--> in the _config.yml file and in front matter, but it doesn't matter where I put it <!–more–>.
Upon request {{ post.excerpt }} I get all content 🙃
