How to add "Read More.." on blogger (Tutorial)

Crazy about BLOGSPOT ???
Someone ever said:
I turned on the "full post" option in my Blogger settings and I can't find it anymore. I tried to find it somewhere on the internet but there are many tutorials with code changing only. But I'm pretty sure there is (or was) an option in Blogger for that. I want to show only beginning of my post with that "Read more..." thing on the bottom and I can't figure out how..

It just like what i've experienced before but now this i will show you some easy trick to add "read more" on our post:

1. Write something on your page and after you done click "insert jump break" button..

2. Then your post will be like this.

3. If you clik the "read more" it will show you full post.

4. Done..
