Blogger: How to add Excerpts

I was looking for this one for my blogger blog: How to display in the Blog Homepage not the full blog posts but only a preview/excerpt of the posts with a Read more link?

I have found the answer here:

http://blogaholicdesigns.com/tutorials/how-to-add-post-excerpts-on-blogger/

It is very easy (it has changed a bit with blogger update)

Simply add a page break now called insert jump break where you want the excerpt to end.

The blog list looks then like:

with a read more link.

Note: It doesn't add any horizontal line.
