Integrating WordPress with Your Website

There are two common ways of integrating WordPress into your existing site:
One, you can install Wordpress, write your posts, and then use PHP or Javascript to integrate the feed directly into your existing design. The drawback with this is if you want to include any links in the feed (for example, to read the rest of the post or add comments). If they click a link, it has to take them somewhere and by default they'll go to your installation of Wordpress which will most likely look nothing like your existing website.
Two, you can take your existing design, tables or CSS, and create a Wordpress theme that matches your site exactly. Then, apply it to your Wordpress installation and you can now have a "/blog" (or whatever you decide to use Wordpress for) that looks and feels exactly like your website. Thus, while it doesn't actually sound like an integration, the result for your end users is the same: you've added the functionality of Wordpress without sacrificing your design and now offer your users added functionality with total continuity.
