 **Secure BIP39 mnemonic backup using PGP encryption and QR codes**
 
 A client-side web app for encrypting cryptocurrency seed phrases with OpenPGP and encoding them as QR-friendly Base45 frames with CRC16 integrity checking.
 
+**Quick note for Bitcoin users (beginner-friendly):**
+
+- This tool helps you securely back up your Bitcoin seed phrase (BIP39) by encrypting it with OpenPGP and giving you a compact QR-friendly export. You don't need to understand the internals to use it — follow the Quick Start below and test recovery immediately.
+- If you are new to Bitcoin: write your seed phrase on paper, keep copies in separate secure locations, and consider using Tails for larger amounts.
+
 **Live App:** <https://seedpgp-web.pages.dev>

+## 🚦 Quick Start — Bitcoin Beginners
+
+If you're new to Bitcoin, this short guide gets you from zero to a tested backup in a few minutes.
+
+1. Clone the repo and install dependencies:
+
+```bash
+git clone https://github.com/kccleoc/seedpgp-web.git
+cd seedpgp-web
+bun install
+```
+
+1. Build the offline bundle and serve it locally (recommended):
+
+```bash
+make full-build-offline   # builds and verifies dist/
+make serve-local         # start local HTTP server on http://localhost:8000
+# or: bun run serve       # uses Bun server
+```
+
+1. Open your browser at `http://localhost:8000`, generate a seed, write it on paper, then encrypt/export using the app.
+
+2. IMPORTANT: Test recovery immediately — import the backup into the app and confirm the seed matches.
+
+Notes:
+
+- Always store the written seed (paper) securely; treat it like cash.
+- For larger amounts, follow the Tails air-gapped instructions in the `doc/TAILS_OFFLINE_PLAYBOOK.md` file.
