  • proficiency with plain text editing, Git, and Bash

Hi @debaa, yes — this is not a program for absolute beginners, but an opportunity for growing your skills in a professional setting given some prior experience. We prefer candidates who have already contributed to the Nix ecosystem, but this is not a strict requirement if you know your ways around related activities.
