+Instructions to reset / update the deployments
+
+## Login
+
+* Log in as `dev` user on the deployments VM
+
+* All the deployments are placed in the `/srv` directory:
+
+  ```bash
+  cd /srv
+  ```
+
+## stage0 laconicd
+
+* Deployment dir: `/srv/laconicd/stage0-deployment`
+
+* Fetch and build with updated source code:
+
+  ```bash
+  # laconicd source
+  cd ~/cerc/laconicd
+
+  # Pull latest changes
+  git pull
+
+  # Confirm the latest commit hash
+  git log
+
+  # Rebuild the containers
+  cd /srv/laconicd
+
+  laconic-so --stack ~/cerc/fixturenet-laconicd-stack/stack-orchestrator/stacks/fixturenet-laconicd build-containers --force-rebuild
+  ```
+
+* Reset the data directory:
+
+  ```bash
+  # Stop the deployment
+  laconic-so deployment --dir stage0-deployment stop --delete-volumes
+
+  # Remove and recreate the required data dir
+  sudo rm -rf stage0-deployment/data/laconicd-data
+  mkdir stage0-deployment/data/laconicd-data
+  ```
+
+* Restart the deployment:
+
+  ```bash
+  laconic-so deployment --dir stage0-deployment start
+
+  # Follow logs for laconicd container, check that new blocks are getting created
+  laconic-so deployment --dir stage0-deployment logs laconicd -f
+  ```
+
+* Since the stage0 laconicd chain has been reset, reset the faucet deployment with new faucet key:
+
+  ```bash
+  cd /srv/faucet
+
+  export FAUCET_ACCOUNT_PK=$(laconic-so deployment --dir /srv/laconicd/stage0-deployment exec laconicd "echo y | laconicd keys export alice --keyring-backend test --unarmored-hex --unsafe")
+
+  cat <<EOF > laconic-faucet-deployment/config.env
+  CERC_FAUCET_KEY=$FAUCET_ACCOUNT_PK
+  EOF
+
+  # Restart the deployment
+  laconic-so deployment --dir laconic-faucet-deployment stop
+
+  laconic-so deployment --dir laconic-faucet-deployment start
+  ```
