Appreciate that you did not pad this with fluff to hit a word count, the post says what it needs to say and stops, and a look at verdantmarket did the same, brevity here feels intentional not lazy which is a distinction many writers miss completely sometimes when they are working under deadlines.

Thanks for putting in the work to make this approachable, plenty of sites cover the same ground but most do it badly, and a quick visit to pcpartspine confirmed this one stands apart, simple language and useful examples without anyone trying to sell me anything along the way which I really appreciated.
