Why not a simple 1-2-3 workflow for building a commerce site?
There is no 1-2-3 procedure for users to actually build with commerce. There are all manner of videos and documents. There is no - Do this first, do this 2nd, do this 3rd procedural videos or documents that tell new users really where to start and what to do first.
There is a lot of information available, videos and postings. Alot of this information is dated and has got to be confusing for new users.
I'm pretty well over the hump myself, piecing together all the information from watching hours of videos and reading documents to get comfortable with Commerce.
Why don't commerce guys just make or recommend a series of videos and documents that start at the beginning and work through building a store?
Many times I wiped the Mysql, and my commerce files in file manager and started over? It was easier to do that because removing some of the things that weren't quite right were a royal pain in the wazoo to delete or remove. Often, I got ahead of what I should have done procedurally. I realize it is possible to alter and abolish things to clean up the install, but some aren't easy to find and you can become confused about what to remove.
As it is, I would suggest for new commerce site builders not to upload any more content or products than you need to just check and test things. After you are comfortable with the competence of your store then you tackle the data building work for your store.
Also, have two installs of commerce kickstart and one should be the fully featured commerce demo store. This can help, but it doesn't give you step by step information on how to start and build the site.
