 # Binary will be at ./target/release/cdk-cli
 ```
 
+### Build with Optional Features
+```bash
+# With Tor support
+cargo build --bin cdk-cli --release --features tor
+
+# With SQLCipher encryption
+cargo build --bin cdk-cli --release --features sqlcipher
+
+# With Redb database
+cargo build --bin cdk-cli --release --features redb
+```
+
 ## Quick Start
 
-### 1. Add a Mint
+### 1. Check Your Balance
 ```bash
-# Add a mint (use a real mint URL or start your own with cdk-mintd)
-cdk-cli wallet add-mint http://127.0.0.1:8085
+# View your current balance across all mints
+cdk-cli balance
 ```
 
 ### 2. Mint Tokens
 ```bash
-# Create a mint quote for 100 sats
-cdk-cli wallet mint-quote 100
+# Create and mint tokens from a mint (amount in sats)
+cdk-cli mint http://127.0.0.1:8085 100
+
+# Or with a description
+cdk-cli mint http://127.0.0.1:8085 100 "My first mint"
 
-# Pay the Lightning invoice shown, then mint the tokens
-cdk-cli wallet mint <quote_id>
+# The command will display a Lightning invoice to pay
+# After payment, tokens are automatically minted
 ```
 
 ### 3. Send Tokens
 ```bash
-# Send 50 sats as a token
-cdk-cli wallet send 50
+# Send tokens (you'll be prompted for amount and mint selection interactively)
+cdk-cli send
+
+# Or specify options directly
+cdk-cli send --mint-url http://127.0.0.1:8085 --memo "Payment for coffee"
 ```
 
 ### 4. Receive Tokens
 ```bash
 # Receive a token from someone else
-cdk-cli wallet receive <cashu_token>
+cdk-cli receive <cashu_token>
+
+# Receive from untrusted mint with transfer to trusted mint
+cdk-cli receive <cashu_token> --allow-untrusted --transfer-to http://127.0.0.1:8085
 ```

 ```
 
-### Token Management
+### Advanced Features
+
+#### Blind Authentication (NUT-14)
+
 ```bash
-# List all tokens
-cdk-cli wallet list-tokens
+# Mint blind authentication proofs
+cdk-cli mint-blind-auth <MINT_URL> --amount <AMOUNT>
+```
 
-# Check token states

+
+```bash
+# Login with username/password
+cdk-cli cat-login --username <username> --password <password>
 
-# Restore wallet from seed
-cdk-cli wallet restore --seed <seed_words>
+# Login with device code flow (OAuth-style)
+cdk-cli cat-device-login
 ```
 
 ## Configuration
 
+### Storage Location
+
 The CLI stores its configuration and wallet data in:
-- **Linux/macOS**: `~/.config/cdk-cli/`
-- **Windows**: `%APPDATA%\cdk-cli\`
+- **Linux/macOS**: `~/.cdk-cli/`
+- **Windows**: `%USERPROFILE%\.cdk-cli\`
+
+You can override this with the `--work-dir` option.
+
+### Database Options
+
+The CLI supports multiple database backends:
+
+#### SQLite (default)
+```bash
+cdk-cli --engine sqlite balance
+```
+
+#### SQLCipher (encrypted SQLite)
+```bash
+# Requires building with --features sqlcipher
+cdk-cli --engine sqlite --password mypassword balance
+```
+
+#### Redb
+```bash
+# Requires building with --features redb
+cdk-cli --engine redb balance
+```
+
+### Seed Management
+
+The wallet seed is automatically generated and stored in `<work-dir>/seed` on first run. This seed is used to derive all keys and can be used to restore your wallet.
+
+**Important**: Back up your seed file securely. Anyone with access to the seed can spend your tokens.
 
 ## Examples
 
 ### Complete Workflow Example
+
 ```bash
 # 1. Start a test mint (in another terminal)
 cdk-mintd
 
-# 2. Add the mint
-cdk-cli wallet add-mint http://127.0.0.1:8085
+# 2. Mint some tokens
+cdk-cli mint http://127.0.0.1:8085 1000 "Initial mint"
+# Pay the displayed Lightning invoice
+
+# 3. Check balance
+cdk-cli balance
 
-# 3. Create a mint quote
-cdk-cli wallet mint-quote 1000
+# 4. Send some tokens
+cdk-cli send
+# Follow interactive prompts
 
-# 4. Pay the Lightning invoice (if using real Lightning backend)
-# or wait a few seconds if using fake wallet
+# 5. The recipient can receive with:
+cdk-cli receive <cashu_token_string>
+
+# 6. Pay a Lightning invoice
+cdk-cli melt
+# Follow prompts to enter invoice
+```
 
-# 5. Mint the tokens
-cdk-cli wallet mint <quote_id>
+### Multi-Mint Setup
+
+```bash
+# Mint from multiple mints
+cdk-cli mint http://mint1.example.com 5000
+cdk-cli mint http://mint2.example.com 3000
+
+# Check balance (shows breakdown by mint)
+cdk-cli balance
+
+# Transfer between mints
+cdk-cli transfer \
+  --source-mint http://mint1.example.com \
+  --target-mint http://mint2.example.com \
+  --amount 2000
+```
 
-# 6. Check balance
-cdk-cli wallet balance
+### Payment Request Workflow
 
-# 7. Send some tokens
-cdk-cli wallet send 100
+```bash
+# Recipient creates a payment request
+cdk-cli create-request --amount 1000 "Payment for services"
+# Copy the payment request string
+
+# Sender pays the request
+cdk-cli pay-request <payment_request_string>
+```
+
+### P2PK (Pay to Public Key) Usage
+
+```bash
+# Send tokens locked to a public key
+cdk-cli send --pubkey <recipient_pubkey> --required-sigs 1
 
-# 8. The recipient can receive with:
-cdk-cli wallet receive <cashu_token_string>
+# Recipient receives with their private key
+cdk-cli receive <cashu_token> --signing-key <private_key>
 ```
 
-### Working with Multiple Wallets
+### HTLC (Hash Time Locked Contract) Usage
+
 ```bash
-# Create wallets for different purposes
-cdk-cli wallet new --name savings
-cdk-cli wallet new --name daily
+# Create a preimage and hash (externally)
+# hash = SHA256(preimage)
 
-# Switch between wallets
-cdk-cli wallet set-default savings
-cdk-cli wallet balance
+# Send with HTLC
+cdk-cli send --hash <hash> --locktime 1700000000
 
-cdk-cli wallet set-default daily
-cdk-cli wallet balance
+# Recipient receives with preimage
+cdk-cli receive <cashu_token> --preimage <preimage>
 ```
