Coding isn't for everyone, but sometimes you can get involved in a coding project just by contributing good suggestions/bug reports to github.
Be thoughtful about how you report things - if you're reporting a bug, add as much detail as you can to help the devs recreate it; if you're suggesting a feature, make a solid case for why the application might benefit from it, think about potential issues it might solve (or cause), consider how you might address users who don't want that feature (make optional).
It is extremely satisfying to see an issue you've reported get fixed or a feature you've suggested get implemented. It gives you a stake in the project, something you won't often get on the corporate-owned platforms.
