You now have a blank file with the very minimum loaded. From here on out, we should insist on only adding clean content to the template. In essence, we should aim to create a fresh start for every new project. Just keep in mind: Junk In, Junk Out!
Once you've started a template, you'll want to assign it as your default template and start using it either for a real project or as a means to test your latest additions.
Of course, we still have a long way to go.
