Static Site into SilverStripe Theme
Create a new folder to hold your new theme, lets call it pandaux!
Update config.yml to point to your new theme.
Declaire your theme as the new theme:
SSViewer: theme: 'pandaux'
Add the default SilverStripe theme structure:
Paste your new markup into Page.ss and rebuild and flush your site.
Update all file references to point to $ThemeDir as the source, for example replace all references.
<img src="images/logo.png" /> becomes <img src="$ThemeDir/images/logo.png" />
Refresh your page, and you should get your new theme's template.
