To setup the node for joining Hero Testnet, first we have to join the Avalanche Fuji testnet then install subnet-evm to plugins with the correct VM ID.
# First download go
# install the version > 1.20.2
wget https://go.dev/dl/go1.20.2.linux-amd64.tar.gz
# install go
sudo tar -C /usr/local -xzf go1.20.2.linux-amd64.tar.gz
# add go to $PATH by using avalanche/validators/.profile
# copy the content to the last line of user .profile file
echo "export PATH=$PATH:/usr/local/go/bin:/home/admin/go/bin" >>> .profile
# use updated .profile
source .profile
