Work Smarter, Not Harder: Template your project configs!
So the title here is a touch clickbaity. If you mainly work on open source, or if you don't work for a company with enough consistency that your config files look largely similar project-to-project, this blog post is not for you. However, if you work somewhere where you feel setting up new projects & updating existing ones ends up being a copy-paste exercise of "what setting did Project A use?" and "what was that thing I did that fixed this in Project C?"... Maybe give this a read.
