+## Demo notes for signer against aws regtest cln node
+
+### ESP32
+
+- Log in to the ubuntu machine, launch terminal, and `cd code/sphinx-key/sphinx-key`.
+- Then launch `clearstorage`, and do a `ctrl-c` when you see the message `NVS cleared!` in the logs.
+- Launch `buildkey`. This builds the signer software that will run on the esp.
+- `flashkey`. This writes the signer software to the esp.
+- Then do `mon`. Short for monitor, this restarts the ESP, and outputs its logs to the screen.
+- Wait for the message `Waiting for data from the phone!`. The LED should blink green.
+- On your phone connect to the Wifi `sphinxkey`. This is served from the ESP32.
+- Launch the signer setup flow on the sphinx app, and input the following settings:
+
+ESP IP address: `192.168.71.1`\
+Broker IP address and port: `44.198.193.18:1883`\
+SSID: ssid of a local wifi with access to the internet\
+Password: password of the wifi from the previous step
+
+- Once the setup is complete, the message `CONFIG SAVED` should appear. Check in the log right above that all the settings are correct.
+- Press the `RST` button, to the right of the USB cable on the ESP. This does a hard reset of the ESP, and now launches the signer.
+- The LED will first blink yellow while it is connecting to the wifi.
+- When the signer is pinging for the broker, the LED on the ESP blinks purple.
+- On the logs, you should see `BROKER IP AND PORT` and `LED STATUS: ConnectingToMqtt`
+
+### CLN AWS
+
+- You'll need 4 windows.
+- SSH all of the windows onto the AWS EC2 instance
+- Run `cleanup` in window A. This completely resets the regtest environment on the AWS instance.
+- Then run `regd` in window A. This launches the regtest node.
+- In window B, do `cd core_lightning_nodes`, and launch `aliced`. This launches alice, a generic regtest CLN node.
+- In window C, launch `alice-cli newaddr`.
+- In the same window, launch `touchwallet && genbtc {address of previous step} && blkdump`
+- In window D, run `cd core_lightning_nodes`, and launch `bobd`. This launches bob, our MQTT remote signer node.
+- Once its pubkey is logged, copy it.
+- Back in window C, run `alice-cli connect {bob pubkey} localhost:20000`.
+- Then `alice-cli fundchannel {bob pubkey} 100000`. This opens a 100'000 sat channel from alice to bob.
+- Then do `blkdump` to generate a bunch of blocks and confirm the channel.
+
+Keysend: `alice-cli keysend {bob pubkey} 1000` ( keysend of 1 satoshi from alice to bob ).\
+Generate invoice: `bob-cli invoice 1000 {label} {description}`\
+Pay invoice: `alice-cli pay {invoice}`\
+Close channel: `alice-cli close {bob pubkey}`\
+Get the node pubkey: `alice-cli getinfo`\
+List the utxos of the node: `alice-cli listfunds`
+List the peers and channels of the node: `alice-cli listpeers`
