State what help would be valuable, outline scope, label skill levels, and share how decisions will be made. Provide contribution guidelines and a friendly code of conduct. Clear onboarding reduces friction and encourages shy, thoughtful contributors to raise a hand.
Keep a living list of questions, gaps, and curiosities that invite others to explore. Tag priority, difficulty, and context. This practice channels spontaneous interest into meaningful progress, while offering newcomers an easy, respectful way to make a first contribution.
