# Install script for Binance Chain

#   - Light Node client (lightd)
#   - Installs both testnet and prod

# Note: this is based on current structure of `node-binary` repo, which is not optimal
# - The installer script is a hack to simplify the installation process
# - Our binaries should eventually be refactor into a `apt` or `npm` repo, which features upgradability
# - We should not rely on folders for addressing (instead use git branches for versions)
