Integrating

No, there is no simple way of doing it. (BTW, the site linked to your name is down).

If you want just the posts to appear in an existing site, you can use the Loop >> https://codex.www.ads-software.com/The_Loop
Or you can create a theme based on your site’s design:
https://codex.www.ads-software.com/Theme_Development
https://codex.www.ads-software.com/Blog_Design_and_Layout > see the themes and templates

To get a quick overview how the template files build a theme, see this anatomy:

Thanks, I’ll try those links out and I’ve just checked the site and its not down.

It looks like The Loop is what I need to use, thanks. Could someone explain the loop to me?

That’s why we have the Codex, so we don’t have to explain it 1,000 times for every user when they ask here in the forum ??

Everything is there what you need to know. Also, it is very useful to read the related pages linked in the text and/or at the bottom.

If using The Loop can I still have the catogry and archives link on the page of my website for example in another iframe? As well as other plug ins?

Yes. Anyway in order to have the Loop functional in a .php file you have to have at the very top of that file – above anything else this:
<?php
require('./path-to-your-blog/wp-blog-header.php');
?>

and having this all the WP functions, template tags, plugins etc. will be working on that file.

I am going to use The Loop to integrate WordPress into my site but I use external stylesheets does anyone know where I can get a template one I can use to include wordpress in it? Thanks

How do I put the catorgries on the other pages after usign that code above??

Doesnt matter, I am using cutenews instead
