Because it's completely unrealistic that a person who has no programming experience, even worse even no basic HTML experience will have familiarity with a Gemfile, how to hide access keys from a repository, etc.

If you think that that information is something you can understand, internalize and actually make work in less than 5 days you're delusional.

It doesn't say she understands it, could just be a copy paste from a tutorial right?

I highly doubt that. When I first started programming it took me upwards of a day to have a simple Windows Form that had two textboxes and displayed a Message Box saying "Hello" + textBox1.Text + " and " + textBox2.Text. Even copy and pasting didn't work.

Perhaps the state of tutorials and online help (stack overflow etc) are much better than in your day. I know they are compared to mine.

Perhaps she coppied the whole project and then just went back through it, changing things and if they didn't work reverted.
