python3
command is Python 3.8 or newer. For instance:
# For RHEL 8
yum install -y https://zato.io/repo/stable/3.2/rhel/zato-3.2-rhel8.rpm
# For RHEL 9
yum install -y https://zato.io/repo/stable/3.2/rhel/zato-3.2-rhel9.rpm
That concludes the process - you can refer to the main documentation index now.
