#!/bin/bash
# Set up a Gaia service to join the provider chain.

# Configuration
# You should only have to modify the values in this block
# * Keys
#    The private validator key and node key operations are provided in case you have a pre-existing set of keys.
#    If you want to generate these keys as part of the setup, comment out the "Replace keys" section.
# * Binary
#    The binary for the amd64 architecture is set by default.
#    If you are using a different architecture, visit the gaia releases page for an adequate link.
#    If you want to build from source, uncomment the "or install from source" section
