Hello there and welcome aboard.
Don’t worry there are WC guru’s aplenty here, but I’m not one of them.
And which tutorials are you following?
is it from here,
and lesson 5 there?
if so, did you read this warning/guide right at the beginning?
So its mainly about creating a THEME for a shop…not a shop itself.
helpful huh? if you dont know your way around WP and WC.
If so, I just downloaded the Finished and html versions of the projects from Github and they dont contain any images - though there might be links to them online.
I shall have a look too, if no developer chimes in to point you in the right direction for those assets.
Which version of PG.
Which version of WP and which version of WC are you working with?
So that should help address some of the vagueness 
A wordpress is a can of worms if you dont know it. People will point your to its documentation
AKA
The CODEX
Which is huge and demoralising.
This …thing
https://codex.wordpress.org/Main_Page
SO maybe do some of the beginner WP stuff first and tutorials on how WP works with PG.
Also are you using PG WP or the PG plugin for wp, on a local or remote server? just asking for paths to files etc for your missing items etc.
And how familiar are you with the PG interface itself?
and its WP interface and stuff?
Just asking because in order to use it correctly you need to know about loops and such like and where/how to add WP actions to the site content in the correct place in the PG interface.
Hence I guess that is why you’re doing the tutorial
But is it to learn PG
Learn WP
Learn WC
?
if its all at the same time, …yeah!
Thats a bit full on.
Also, for @matjaz
the link at the bottom of the Github project site for the HTML finished version
labelled *Shop Starter Course
shown here
links to the following missing Pinegrow documentation page
which suggests clicking on the following link to the documentation for Pinegrow V2.x site.
https://pinegrow.com/docs/woocommerce/starter-shop-creating-a-custom-woocommerce-theme/
but…if you DO follow that link to the PG V2 docs… and V3 and 4… maybe 5?>…aargh!!!
You get this beauty!
So where have all the docs from docbeta gone?
that now means that the docs collation posts such as
are now…well…fudged.
That post, mentioning some docs issues is um, from 2018 btw… just saying.
SO, gone full circular, back to the versioned documentation debate 
Finally, entering woo commerce tutorial into our documentation site,
yields no relevant results.
