+# Terminal Portfolio
+
+A minimalist landing page that points visitors to an SSH-accessible portfolio (`ssh portfolio@keshavanand.net`). The webshell behind the SSH endpoint is a separate concern; this repo is just the marketing/landing surface.
+
+## Stack
+
+- Vite + TypeScript (vanilla, no framework)
+- Plain CSS, JetBrains Mono via Google Fonts
+- Two pages: `index.html` (homepage) and `docs.html` (how it works)
+
+## Structure
+
+- `index.html` — homepage markup
+- `src/main.ts` — homepage typewriter + copy-to-clipboard logic
+- `src/style.css` — homepage styles (dark, dot-grid background, soft glow)
+- `docs.html` / `src/docs.ts` / `src/docs.css` — docs page
+- `vite.config.ts` — multi-page build config; dev server on `0.0.0.0:5000` with `allowedHosts: true` for Replit
+
+## Design notes
+
+The homepage intentionally avoids busy background animation. It uses:
+- A static CSS dot grid + a single soft radial glow (no JS animation loop)
+- A short typewriter intro for the SSH command with a humanized cadence
+- A blinking block caret that persists after typing
+- Subtle opacity-only fade-ins (no transform-based slide-ins)
+- Honors `prefers-reduced-motion`
+
+## Run
+
+- Workflow `Start application` runs `npm run dev` on port 5000.
