This would be a great introduction if it specified at the top that it pertained to GNU make. I had suspected as much, but I wasn't able to confirm for sure until I got to the end and saw that you linked to the GNU make manual for further reading.
I'll throw you an upvote anyway because I suspect most of your target audience is using the GNU toolchain, and because you posted this on your own website instead of using Medium. :)
