After a few weeks trying to figure out how to make a blog with Gatsby, I finally got it.
Learning to do the programming part wasn't the hardest. The Gatsby community has a lot of contributers and I would suggest that if you are looking into how to do this stuff, you look at recent examples. The industry changes too much to be reviewing how to install old programs. Keep it to within a year and visit the Node.js and other applicable sites to make sure you are running the up to date (and stable) stuff.
