users git repository should not be empty.
when I started my first pipeline I clone my nico/nico repository but it came up empty
it took me 30 minutes to figure out crunch_scripts was needed (yes, I know it's in the docs and also that there was an error saying so!... but I was getting familiar with 10 other things at the same time)
It will be better to have a README file and that directory created with a "hello.py" so it's much faster to get up and running the first pipeline.
