The best approach is to have a play around with Kata (try out some of the more advanced options, build a custom rootfs, enable debug, try Kata with Firecracker, k8s, etc).
Feel free to just come and chat to us and I'm sure between us we can find an area that interests you whether that be PR reviews, bug triage, testing packages / new distros / new platforms, writing code or tests, writing documentation and blogs, packaging, helping to improve the CI, finding ways to improve our process, writing new tooling ... the list of opportunities goes on and on ;)
Welcome to the team!
Cheers,
James
