# ProofPoll Always-On Node Setup
#
# Run this on a fresh GCE e2-micro instance (Debian/Ubuntu).
# Prerequisites: SSH access, the ProofPoll hApp file.
#
# Usage:
#   1. Create GCE instance:
#      gcloud compute instances create proofpoll-node \
#        --zone=us-central1-a \
#        --machine-type=e2-micro \
#        --boot-disk-size=10GB \
#        --image-family=debian-12 \
#        --image-project=debian-cloud \
#        --tags=proofpoll-node
#
#   2. SSH in and run:
#      sudo bash setup.sh
#
#   3. Copy the hApp file to the server:
#      gcloud compute scp ../src-tauri/resources/proofpoll_v1_3_happ.happ \
#        proofpoll-node:~/node/ --zone=us-central1-a
#
#   4. Install the hApp:
#      bash install-happ.sh
