I just installed it and took a brief look at it, so I might have misunderstood something.
1. Install it
2. Prepare some content you want to display. Complete with HTML and PHP-code. Save it under /modules/cjaycontent/content/
3. Go to admin/blocks, klik on CJayContent (for some reason it doesn't show up in the lefthand column in the admin page).
4. Fill in the fields under Add new content connection and select the file, you want to dislpay.
5. Click Add connection.
6. Take a look at your frontpage.
This should give you a starting point from which to explore the rest by yourself.
