Why Developers Don't Read READMEs

Developers are the world's most efficient skimmers. When someone lands on your repo, they're running a rapid mental triage: What does this do? (5 seconds) Can I run it? (10 seconds) Should I trust it? (5 seconds) If they can't answer all three within 20 seconds, they close the tab and move on. They don't owe you a careful read. They're choosing between your project and ten others. Most READMEs fail the triage test because they're written from the author's perspective, not the reader's. The author knows how it works, so they explain how it works. The reader doesn't know if it works at all, so they need to know what it does first. That's the gap. Let's close it. The README That Passes the 20-Second Test Every high-performing README follows a version of the same structure. The order is not arbitrary — it mirrors the reader's decision-making process. 1. One-Line Description (Not Your Project's Name) The name is already in the repo title. The first line of your README should be a plain-language sentence of what this thing does . ❌ SuperCache v2.0 ✅ A zero-config in-memory cache for Node.js that cuts database eat time by 60%. If your one-liner doesn't tell me what problem you're solving, I'm already skimming toward the exit. 2. A 30-Second "Why This Exists" Paragraph Two to four sentences. What problem does this solve? Who is it for? Why this over the alternatives? This is not a marketing pitch. It's a fast filter. You want the right people to know immediately that this is for them — and the wrong people to know it's not. 3. Demo / Screenshot First — Before Installation This is the most skipped section in most READMEs. It shouldn't be. A GIF, screenshot, or three-line code output does more work than five paragraphs of description. Show me what success looks like before you tell me how to get there. If I can see that your output solves my problem, I'll read every word of your installation guide. 4. Installation — Zero Assumptions Assume your reader is smart but unfamiliar
