You seem to imply that "contributing to open source projects" must mean coding, but there's lots of tasks that you can do that are not coding.

* Answering a question about PostgreSQL configuration files on Stack Overflow contributes to the PostgreSQL project.

* Tweeting about your favorite underrated Vim keybinding contributes to the Vim project.

* Supporting Jason Donenfeld on Patreon contributes to the Wireguard project.

* Proofreading the Linux kernel documentation contributes to the Linux project.

* Contributing a translation of the Blender GUI into a less common language contributes to the Blender project.

* Designing a wallpaper artwork for the Plasma desktop contributes to the KDE project.

* Writing a detailed bug report for a Sway crash contributes to the Sway project.

And so on, and so forth.
