I have never written code. Can I still contribute to the Malairte project?

Absolutely, and most contributors are not full-time developers. The project needs people to improve documentation, report bugs clearly, answer beginner questions in the chat, test new releases on their own hardware, and translate the wallet and website into other languages. Every one of those tasks makes the project better and none require programming. A good first step is to read the contributing file, lurk in the community chat for a few days to learn the culture, then fix one small thing, like a confusing sentence in the install guide. Small, reliable contributions get noticed and mentored. The fastest way in is often through your local meetup, where an experienced member can walk you through your first contribution in person.
