Topic: Install Blog in existing page

I have an existing rails web page that i want to  add a blog to.  I could easily just get away with writing it from scratch, but i'd like to use Typo just to learn how to integrate two separate apps.  How can i take typo, and merge it into my existing site?  Is there any tricks to it, or do you just dig into it and go?

Sorry if this has been posted before, i searched briefly but i wasn't really sure what to search for.
