About the hello holo tutorial - beginner

https://developer.holochain.org/docs/tutorials/coreconcepts/hello_holo/

Hi there

I am using Ubuntu 20.04 LTS (first time Ubunutu user)
My laptop is a dual core i5-6300u with 8gb RAM.

I start out in the nix shell to initiate cc_tuts (hc init cc_tuts)

When I package this app I do not get the same hash result as is mentioned in the hello holo tutorial.

From here I get stuck in proceeding the beginners tutorial.

Who can run me through this?

I also want to understand the folder layout.

Thanks!

DaYa
