Earlier quoted context omitted.
Ctl-Shift-P is used in VSCode as well as Sublime. And then, "Install Package" Or through the Gui - "Preferences --> Package Control"
Sure, I find that every time I google for how to do it :-) In VSCode, I can browse info about packages without having to remember a thing aside from "one of the six big icons on the left is 'Extensions'". One mouse click, start typing, click anything that looks like it might be good, get a ton of info and an "install" button. There are filters! So I can simply sort by "most popular" if I want, or by name, or a bunch…
I do love the fact that, with Sublime, that 75%+ of the time when I want to do something, say, pretty-print a JSON text document, it's just:
Ctl-Shift-P, "json" (Don't see anything obvious)
[hit backspace to clear json] "Install Package", "json"
See the "Pretty Print" option, install it in 2 seconds, and on my way.
