Q:

How to call post title and post summary to other part of site? 

My blog is installed at /posts of my site.  
It's not a mistake; I wanted to be like that.  But now my homepage looks somewhat empty.  Here I want to call the title of my blog to my homepage, with a link to the original post at /posts, followed by a summary of the post.  
I don't know where to start; I actually have no any technical understanding of WordPress and how it works. 
My blog is currently installed at http://sntsh.com/posts/.
