How do I embed wordpress into existing website (html)

This is a straight forward question. I need to put a wordpress blog into an htlm website. How would I go about doing that? I would assume by now there is some embedding code out there that would allow wordpress to be used in this manner.

To clarify, I don’t want the main website to redirect to the wordpress page. I need the wordpress inside the website layout, similar to how there are embedding options for youtube, twitter, etc.

Thank you!
