+git pull
+
+sudo systemctl stop solver
+sudo systemctl stop mediator
+./stack boot # THIS WILL WIPE OUT GETH AND ALL THE BLOCKCHAIN DATA
+```
+
+now we need to edit the code to set the new default controller contract address from `stack boot` above
+https://github.com/bacalhau-project/lilypad/blob/main/pkg/options/web3.go#L21
+
+commit and push and then use the resulting binary for the control plane and resource providers
+
+```
+go build
+
+sudo mv lilypad /usr/bin/lilypad
+
+sudo systemctl start solver
+sudo systemctl start mediator # not used currently
+```
+```
+journalctl -f -u solver
+```
+
+### gpu node(s)
+
+```
+ssh node05.lukemarsden.net
+```
+
+github should have build the binary by now, go download the latest one from https://github.com/bacalhau-project/lilypad/releases
+
+```
+cd /app/lilypad
+## CHANGE THE HASH BELOW TO THE LATEST FROM RELEASES PAGE!!
+wget https://github.com/bacalhau-project/lilypad/releases/download/v2.0.0-f70e4e1/lilypad-linux-amd64
