 6. Now you can run `nixops deploy -d bitcoin-node` and it will connect through the ssh tunnel you established in step iv. This also allows you to do more complex ssh setups that `nixops ssh` doesn't support. An example would be authenticating with [Trezor's ssh agent](https://github.com/romanz/trezor-agent), which provides extra security.

+Initialize a Trezor for Bitcoin Core's Hardware Wallet Integration
+---
+
+1. Enable Trezor in `configuration.nix`
+
+	Change
+	```
+	# services.hardware-wallets.trezor = true;
+	```
+	to
+	```
+	services.hardware-wallets.trezor = true;
+	```
+
+2. Deploy new `configuration.nix`
+
+	```
+	nixops deploy -d bitcoin-node
+	```
+
+3. Check that your nix-bitcoin node recognizes the Trezor
+
+	```
+	nixops ssh operator@bitcoin-node
+	lsusb
+	```
+	Should show something relating to your Trezor
+
+3. Start the Trezor in bootloader mode
+
+	Trezor v1
+	```
+	Plug in the Trezor with both buttons depressed
+	```
+
+	Trezor v2
+	```
+	Start swiping your finger across the Trezor's touchscreen and plug in the USB cable when your finger is halfway through
+	```
+
+4. Update your Trezor's firmware
+
+	```
+	trezorctl firmware-update
+	```
+	Follow the on-screen instructions
+
+	**Caution: This command _will_ wipe your device. If you already store Bitcoin on it, only do this with the recovery seed nearby.**
+	
+5. Set up your Trezor, if this is a fresh device
+
+	```
+	trezorctl reset-device -p
+	```
+	Follow the on-screen instructions
+
+6. Find your Trezor
+
+	```
+	hwi enumerate
+	hwi -t trezor -d <path from previous command> promptpin
+	hwi -t trezor -d <path> sendpin <number positions for the PIN as displayed on your device's screen>
+	hwi enumerate
+	```
+
+7. Follow Bitcoin Core's instructions on [Using Bitcoin Core with Hardware Wallets](https://github.com/bitcoin-core/HWI/blob/master/docs/bitcoin-core-usage.md) to use your Trezor with `bitcoin-cli` on your nix-bitcoin node
