+Rophako has a dual templating system: when it wants to show a page, it will prefer to use *your* custom HTML template to render that page, before falling back to its default built-in pages (including pages for plugins such as the Blog or Photo Albums).
+
+So, when Rophako wants to display a web page to the user, it looks in various locations for it:
+
+1. First it will check the user's custom template folder (the `SITE_ROOT` variable from `config.py`)
+2. Then it will check its built-in (fallback) template folder (`rophako/www/`)
+3. Then it will check the various plugin template folders (i.e. `rophako/modules/blog/templates`)
+
+So as an example, the Blog plugin might want to show the template `blog/entry.html` to the user. It will first search for a file named `blog/entry.html` in your `SITE_ROOT`, and if it doesn't find it, it will look in the built-in default site; if it doesn't find it, it will scan through the plugins' template folders (and will eventually find it at `rophako/modules/blog/templates/blog/entry.html`).
+
+All of the core features of Rophako (user account, blog, photo albums, comments, etc.) exist in the default site and plugin folders, so the CMS is already fully functional out-of-the-box. You can override files in the default site by putting files with the same name in your `SITE_ROOT` folder. For example, the default `SITE_ROOT` is set to the "site/www" folder in the git repo, and if you put a file at `site/www/layout.html` there, it will change the web design template for the Rophako site. A file at `site/www/index.html` will change the index page of your site away from the default.
