Spec: a README and demo that make your project legible to a stranger

A finished project with no README, or a README that's just the default framework boilerplate, asks a stranger (a recruiter, a hiring manager, an interviewer prepping beforehand) to do the work of figuring out what they're even looking at. Most won't. This is the project on this list that isn't new code — it's making the code you've already written actually count.

The brief

Write a real README for a project you've already built (from this list or elsewhere), structured so someone with zero context understands what it is and why it exists within the first few lines.

Requirements

• One sentence at the top stating what the project does and, ideally, why — not the tech stack first, the point first.
• A way to see it working without setting it up — a screenshot, a short screen recording, or a live deployed link. Someone skimming a list of projects will look at this before reading a word of the README.
• How to run it, for the smaller number of people who do want to dig in — real setup steps, tested by actually following them yourself on a clean checkout.
• One honest limitation or thing you'd do differently — this is the line that separates a README written to impress from one written by someone who understands their own project deeply enough to critique it.

Why this is portfolio-worthy

A project's README is frequently the only part of it a busy person reads before deciding whether to look further — it's the highest-leverage half-hour you can spend on a project that's otherwise already finished. Two people with equally solid projects will be evaluated very differently based on this alone.

What to avoid

Don't write a README that only makes sense to someone who already knows what the project is (i.e., you). Show it to someone with no context and watch where they get confused — that's exactly where the README needs to be rewritten, not explained to them verbally.
