There are 2 options to setup Nibiru node (Automatic and manual installation) but i recommend you to use automatic installation because manual installation is not necessary. Automatic installation also prevent you from wrong doing

I'll stick to script written by kj89 for automatic installation. Run this commands:

wget -O nibiru.sh https://raw.githubusercontent.com/kj89/testnet_manuals/main/nibiru/nibiru.sh && chmod +x nibiru.sh && ./nibiru.sh

After installation finished, run this commands to load variables into system

source $HOME/.bash_profile

And then make sure that your node synchronized by running commands below:

nibid status 2>&1 | jq .SyncInfo

Note: if catching_up == false that mean the node has been fully synchronized otherwise you need to wait until node fully synchronized before continue to next step. You can also speed up your node synchronization by using State-Sync provided by PPNV service.
