Implementing wordpress into your layout

I know this questions has been answered many times before, I have spent the last hour looking for it but without luck. Could somone please point in the right direction or tell me what tags I need to implement just the blog into my layout. All I want is the blog to be displayed in my graphical template. Thanks. Also wordpress is in its own directory called blog. So I’d reffer to the blog by going to http://www.mywebsite.com/blog/index.php. So if somone could help me I would much apriciate it. Thanks…
