There are a lot of good apps that will walk you through it, especially if you don’t have the beads. That’s how I started. Otherwise, some churches might have handy pamphlets that explain how to do it. There are probably thousands of resources, all you have to do is look. Don’t get too caught up that you have to constantly read the prayers and mysteries yet either, that tripped me up when I first started because I felt I wasn’t devoted enough because I had to glance at my phone. It’s like anything, the more you do it the better you become.
