#### You can either manually update the settings in the config file or just upgrade to the latest git version and run the installer to select the appropriate option for you:

$ cd \~/mvp-pox-node && sudo git pull && ./etny-node-installer.sh

\*\*\* 1. Automatic = This option will set polygon Mainnet if your wallet has MATIC, otherwise will set bloxberg Mainnet (recommended for most users)

\*\*\* 4. bloxberg Mainnet (ETNY) = This option will set bloxberg Mainnet
