Getting ready - setting up NextCloud

Hi! I ordered my Hv2 last year and am excited by its arrival. Since it is getting delayed, I am wondering if there are any steps I can take to start prepping for the arrival. For example I would like to get my music collection set up and start organizing it … I am wondering if there are any configurations we can use / serve off a local computer to start getting prepped.

I have seen NextCloud referenced … can this be set up ahead of time? Are there any other suites of software/tech that are used with Helm that I can start learning about / getting ready? Thanks!
