Trouble finding correct info :(

I have a website in HTML code and in a seperate folder withen the same domain (www.mysite.com/blog)I have a blog site I installed wordpress this is the most recent version. my only task is: when a new post is posted on my blog site I would like to be able to have the new posts auto updateted on my webpage that of my choosing (HTML)and maybe different part of my pages within the HTML site that are relevant. I contributed to wordpress but the support on this subject is very confusing. so if anyone has accomplished this or of this can be done please let me know.
