+# pyhdwallet v1.0.2
+
+A secure, offline command-line tool for generating and recovering BIP39 HD wallets with support for Ethereum, Solana, and Bitcoin.
+
+## Purpose
+
+pyhdwallet helps you create new wallets or recover from existing mnemonics/seeds, with built-in PGP encryption for secure storage. It's designed for privacy-conscious users who want offline, auditable wallet management.
+
+## Installation
+
+1. Ensure Python 3.11+ is installed.
+2. Clone/download the repo.
+3. Create a virtual environment: `python -m venv .venv && source .venv/bin/activate`
+4. Install dependencies: `pip install -r requirements.txt`
+
+## Basic Usage
+
+Run the tool with a subcommand. For help, use `-h`.
+
+- Generate a wallet: `python ./src/pyhdwallet.py gen --chains ethereum --addresses 3`
+- Recover from mnemonic: `python ./src/pyhdwallet.py recover --mnemonic "your words" --chains bitcoin`
+- Fetch PGP key: `python ./src/pyhdwallet.py fetchkey "https://example.com/key.asc"`
+- Run tests: `python ./src/pyhdwallet.py test`
+
+For detailed examples and security tips, see `playbook.md`.
+
+## Security
+
+- Operates offline by default.
+- Use `--secure-mode` for high-security operations.
+- Always verify PGP keys and run on trusted systems.

 A command-line tool for generating and recovering HD wallets (BIP39) with support for Ethereum, Solana, and Bitcoin. Features offline operation, PGP encryption, and multi-chain address derivation.
 
+**Note**: This tool requires a subcommand (e.g., `gen`, `recover`). Running without one displays help. Use `<subcommand> -h` for detailed options.
