How do you make your repo actually welcoming (not just “open source”)?

[pumpkin-face]

I’ve seen so many repos with zero context, broken setup steps, or silence on PRs — and it’s a total turnoff for new contributors.

What’s one small thing you’ve done (or seen) that made a repo feel genuinely inviting?
→ Was it a GIF in the README?
→ A “first-timers only” issue with hand-holding?
→ A maintainer who replied with “Nice catch!” instead of just “lgtm”?
