"Probably the most common way ..." -> "An easy way to get started ..." or "The easiest way way to get started ..." -- I think we should try to avoid words like "probably" that make the documentation seem unsure about what its teaching.

Also, I totally forgot that `duckpan new` generates a very basic test file for you. So we should probably mention that -- I'm not actually sure if we've mentioned the `duckpan new` feature in the rest of the docs
