 ## Features
 
-- **Certificate of Death** — A4-style layout with cause, last words, repo age, and derived stats
-- **Exports** — Multiple aspect ratios (feed, square, story-style) for Instagram, X, Facebook
-- **Mobile share** — Native share sheet on mobile with story-friendly format
-- **Hall of Shame** — Curated leaderboard of famously abandoned repos
-- **Recently Buried** — Live feed of the latest public burials
-- **Chrome extension** — Tombstone badge injected on any GitHub repo page (MVP)
+- **Certificate of Death** — A4 layout with cause of death, last words, repo age, stars, forks, and language
+- **Algorithmic scoring** — `src/lib/scoring.ts` computes a death index from commit activity, archive status, issue count, and time since last push
+- **Export** — PNG downloads in multiple aspect ratios: A4, Instagram (4:5 and 1:1), X/Twitter (16:9), Facebook feed, and Stories (9:16)
+- **Mobile share** — Native share sheet on iOS/Android with a story-formatted image
+- **README badge** — Embed a `⚰ DECLARED DEAD` shields.io badge linking back to the certificate
+- **Certificate embed** — Full certificate image via `/api/certificate-image/[owner]/[repo]` for GitHub READMEs
+- **Recently Buried** — Live scrolling feed of the latest public burials
+- **Famous Casualties** — Curated graveyard of famously abandoned repos
+- **Rate limiting** — Redis-backed per-IP limiting with graceful fallback
+- **Timeout + race condition handling** — AbortController on every GitHub API call

+**Without any env vars** the app still works fully — you just get GitHub's unauthenticated rate limits (60 req/hr) and the Recently Buried feed is hidden.
 
-> **Note:** The Recently Buried feed requires Upstash Redis (`KV_REST_API_URL` + `KV_REST_API_TOKEN`). Without it, the feed is hidden and the buried counter falls back to the historical baseline.

 ## How we pronounce repos dead
 
 | Step | What happens |
-|------|----------------|
-| Input | You submit a public GitHub URL |
-| Data | The app fetches public metadata via the GitHub API |
-| Score | A death index and narrative are computed in `src/lib/scoring.ts` |
-| Output | Certificate rendered on-screen, exportable as PNG |
-
-Hall of Shame entries are hand-curated; Recently Buried reflects real usage.
-
-## Testing
-
-```bash
-npm test
-```
+|------|-------------|
+| Input | User submits a public GitHub URL |
+| Fetch | App fetches repo metadata + latest commit via GitHub API |
+| Score | `computeDeathIndex()` in `src/lib/scoring.ts` produces a 0–10 death index |
+| Narrative | `determineCauseOfDeath()` picks a cause based on the index and repo signals |
+| Output | Certificate rendered client-side, exportable as high-res PNG |

+The scoring algorithm weighs: time since last commit, archive status, open issues, fork ratio, star count, and whether the last commit message reads like a final sigh.

-## Chrome extension (MVP)
+## Running tests
 
-A MV3 extension lives under `extension/`. It injects a tombstone badge on GitHub repo pages and links to the full certificate.
+```bash
+npm test
+```
+
+Tests cover the scoring algorithm in `src/lib/scoring.test.ts`.
 
-### Load unpacked in Chrome
+## Contributing
+
+Contributions are welcome. Please read [`.github/CONTRIBUTING.md`](.github/CONTRIBUTING.md) before opening a PR.
 
-1. Open `chrome://extensions/`
-2. Enable **Developer mode**
-3. Click **Load unpacked** and select the `extension/` subfolder
+- Use the issue templates for bugs and feature requests
+- CI runs lint, tests, and build on every pull request to `master`
+- Keep PRs focused — one thing at a time
 
-### Test flow
+## Roadmap
 
-1. Open a GitHub repo page (e.g. `https://github.com/vercel/next.js`)
-2. Verify a tombstone badge appears near the repo header
-3. Click the badge to open the full certificate on `commitmentissues.dev`
-4. Navigate to another repo without a full reload; verify no duplicate badge appears
+Items are loosely prioritized. Community PRs welcome on anything marked **good first issue**.
 
-If the API is rate-limited or unavailable, the badge falls back to `Reaper busy`.
+### Near-term
+- [ ] Upgrade to Next.js 16 (planned within one month of launch)
+- [ ] Dark mode
+- [ ] `/api/certificate-image` caching layer (currently no Redis cache)
+- [ ] Repo comparison — bury two repos side by side
 
-## Docs
+### Longer-term
+- [ ] Chrome extension — tombstone badge injected on GitHub repo pages
+- [ ] Language-specific causes of death ("Died of PHP fatigue", "Last seen in CoffeeScript")
+- [ ] Death anniversary emails — opt-in reminders on the date of last commit
+- [ ] API for third-party integrations
 
-- Release notes: `docs/releases/`
-- Screenshots: `docs/screenshots/`
-- Repository conventions: `docs/repository-conventions.md`
+### Won't do (by design)
+- Private repo support — we don't break into houses
+- Accounts / login — the funeral is free and anonymous
+- Monetization — coffee button stays, paywalls don't
