Simplify new project creation

[WasabiFan]

In the project creation tutorial, we currently instruct the user to open the example post from GitHub, copy the content, and then paste it into a new file. It would be easier if we simply gave the content to them on the page and had them copy it from there.

I'd be interested to see if there's something similar to the built-in Gist functionality that would let us host a nicely-formatted code block that would pull from the existing file so we don't have to paste the example content into the tutorial. that's something to look into.

P.S. I noticed some other problems with the project tutorial that I'll be fixing in a PR soon.
