-
-## 🎯 Key Features
-
-### Heir Management
-✅ **Add/Remove Heirs** - Manage multiple beneficiaries
-✅ **Inheritance Percentages** - Set distribution shares (sum must be 100%)
-✅ **Locktime Conditions** - Define when each heir can access their funds
-✅ **Address Validation** - Verify Bitcoin addresses before saving
-✅ **Distribution Summary** - View total inheritance breakdown
-
-### Locktime Transactions
-✅ **Absolute Locktime** - Transaction can only be spent after a specific:
-   - Block height (e.g., `700000`)
-   - Timestamp (Unix timestamp, e.g., `1609459200`)
-
-✅ **Relative Locktime** - Transaction can only be spent after:
-   - **Days**: Use suffix `d` (e.g., `3d` = 3 days from now)
-   - **Years**: Use suffix `y` (e.g., `2y` = 2 years from now)
-
-✅ **Locktime Types**:
-   - **Block-based**: Locktime in blocks
-   - **Time-based**: Locktime in seconds since epoch
-   - **Relative**: Time intervals from current time
-
-### Multi-Signature Support
-✅ **Combine signatures** with existing wallet signatures
-✅ **Configure required signatures** for spending
-✅ **Support for complex multisig** setups with heirs
-

-## 📖 Usage Examples
-
-### Example 1: Simple Heir Setup
-
-1. **Add an heir**:
-   - Address: `bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq`
-   - Percentage: `50%`
-   - Locktime: `1y` (1 year from now)
-
-2. **Add second heir**:
-   - Address: `bc1qw508d6qejxtdg4y5r3zarvary0c5xw7kv8f3t4`
-   - Percentage: `50%`
-   - Locktime: `2y` (2 years from now)
-
-3. **Create transaction**:
-   - Send 0.5 BTC to heir1 after 1 year
-   - Send 0.5 BTC to heir2 after 2 years
-
-### Example 2: Locktime Transaction
-
-```python
-# Create a transaction that can only be spent after 6 months
-from bal_electrum_plugin.locktime import Locktime
-
-locktime = Locktime(
-    type="relative",
-    value="6m",  # 6 months from now
-    unit="blocks"  # or "seconds"
-)
-
-# This transaction will be locked for 6 months
-tx = create_transaction(
-    recipients=[recipient_address],
-    amount=0.1,
-    locktime=locktime
-)
-```
-
-### Example 3: Complex Inheritance
-
-- **Heir 1**: 30%, locktime `1y`
-- **Heir 2**: 40%, locktime `2y`
-- **Heir 3**: 30%, locktime `3y`
-
-Total: 100% distributed over 3 years

-## 🐛 Troubleshooting
-
-### Plugin Not Showing in Electrum
-
-❌ **Problem**: The plugin doesn't appear in Electrum's plugin list
-
-✅ **Solutions**:
-1. Verify you're using Electrum 4.0.0 or later
-2. Check that the zip file contains the `bal_electrum_plugin/` directory
-3. Ensure the directory structure is correct inside the zip
-4. Restart Electrum after installation
-5. Check Electrum logs for errors (Help → Debug → Console)
-
-### Locktime Not Working
-
-❌ **Problem**: Locktime conditions aren't being enforced
-
-✅ **Solutions**:
-1. Verify locktime format: `3d` (days), `2y` (years), or timestamp
-2. Check that the locktime is in the future
-3. Ensure your Bitcoin node supports locktime transactions
-4. Test with a small amount first
-5. Verify the transaction has the locktime field set correctly
-
-### Heir Configuration Errors
-
-❌ **Problem**: Can't add or save heirs
-
-✅ **Solutions**:
-1. Verify Bitcoin addresses are valid (use testnet for testing)
-2. Check that percentages sum to exactly 100%
-3. Ensure locktime values are valid formats
-4. Enable debug mode to see detailed error messages
-5. Check plugin logs for specific error details
-
-### Common Error Messages
-
-| Error | Cause | Solution |
-|-------|-------|----------|
-| `Invalid checksum` | Bad Bitcoin address | Verify the address |
-| `Percentage must sum to 100%` | Invalid heir distribution | Adjust percentages |
-| `Locktime in the past` | Invalid locktime value | Use future date/time |
-| `Plugin not found` | Incorrect zip structure | Check zip contents |
