@vatsal Yes I'm sure "folder-name" : "public/folder-name" means you can use /plugins/your-theme-name/folder-name/whatever
The first parameter correspond to the name that will be used after theme-name/folder, while second parameter means this alias points to path.
@BDHarrington7 No idea, and wouldn't know how to check it. Anyway, I already destroyed the Droplet so I can't answer that question. In a bit I will rebuild a new CentOS droplet and start from scratch.
I think my biggest issue is simply not understanding file and directory paths. I am likely in the wrong folder running commands that expect me to be in another folder, etc.
If I had hair on my head it would be gone by now.
