displaying wordpress on my homepage

i’m sure this has been discussed many many times, and i’ve searched this forum and www.remarpro.com and google etc.

my questions is:
i want to integrate wordpress into my existing homepage, so that my wordpress blog is displayed on my /index.php page.

I’ve found these links:
https://www.jonathanwold.com/tutorials/wordpress_integration/
https://www.transycan.net/blogtest/2005/07/05/integrate/

the links seems to say “integrating into existing website”, but mean creating/modifying themes to match your existing website. maybe i’m missing something…

what i’m interested in learning is how to embed the blog into my current homepage with existing navigation. for example, using the default theme. is this possible, or recommended?

thanks in advance.
