The Blog posts section allows you to display images and text from your four most recent posts.
To specify the "preview" text that appears for each post, use Shopify’s excerpt function in the post editor (Online store > Blog posts > Blog post > Add excerpt).
Add a blog posts section to your home page
Navigate to the Sections tab in the theme editor and select Add section > Blog posts.
Select the blog to display
Assign the blog you want to feature through Select blog. While many stores maintain only one blog (probably called "News") some create multiple to better categorize information–including customer stories, tips, tutorials, and more.
Start by giving your section a Heading. Enable Show border to feature a horizontal line above your blog posts.
