I'm basically just copying good instructions that I've seen in other projects. What this does is add:

• --id option that ensures that benboyter.scc is the ID. Without this benboyter.scc is getting passed as a query instead of as a unique ID. This could potentially cause a similarly named package to get installed.
• --source option to specify that the winget repository should be used.

Personally, I always use the --id option with winget.
