Thanks for catching this. I wonder if we even need this FAQ anymore now that it's a bit easier to manage?

On Discord I already saw two threads with sync. Intellisense wasn't working for them as they forget to run sync (it was for $lib alias). Or they wanted to set it in jsconfig.json themselves. I think same problem will be with custom aliases.

Also a lot of people that used Kit for some time already remember it's in FAQ and when they look there, expect FAQ about aliases.
