Medically retired. Want to give back to Linux. What free pathways exist to help train someone to a level where they can assist with the Linux kernel?

I've been medically retired and now have more free time. As well, I've been daily driving Linux since about 2010. Aside from helping other users in random posts, I have largely been a consumer of Linux.

Over the last few weeks I've seen and read posts leaning towards Linux needing kernel maintainers. While I am not a complete noob, i know I'm not a software engineer.

This leaves me with two questions:


1. What courses or certifications do I need to help maintain the kernel?


2. Is there another way to give back in the meantime?


Thanks
