How to implement a read-more link?

Hi,

Currently my client is using Radix theme for their blog. You can view here. bit.ly/1MFifSY

The home page is set to the blog roll, which contains a snippet from each blog post. But the snippet text for each blog post cuts off abruptly without a “…” or a “click to read more” button.

In the Radix theme options, I can’t find anywhere to turn on or off a button.

I also can’t find a way to extend the length of the blog post preview in order to show the full blog post. In the wp-admin section Appearance > Radix options > Blog, there is a “Excerpt Length Limits” section, but what I want is to remove the limit of the excerpt entirely, or to end the excerpt with a link that says something like “Click to read more.”

However, on the Radix demo site https://starter.radixtheme.com/blog/ the blog posts are displayed in full, so there must be a way to turn this on.

Can you please clarify if the Radix theme currently has these features? If so, how do I configure them?

Thanks.
