Hi Yaroslav,

Thanks for sharing your thoughts!

I would say these command lines are an excellent illustration of how the
two approaches and target audiences are different: datalad may be great for
advanced and tech-savvy users, while openneuro-py aims to providea
 no-frills, easy-to-use access to OpenNeuro. You wouldn't even need to know
about git in order to use it: all you need is an OpenNeuro dataset id and a
Python installation.

Cheers,
