Read the User and Developer Documentation at https://frappe.github.io/schools
The Easy Way: our install script for bench will install all dependencies (e.g. MariaDB). See https://github.com/frappe/bench for more details.
New passwords will be created for the ERPNext "Administrator" user, the MariaDB root user, and the frappe user (the script displays the passwords and saves them to ~/frappe_passwords.txt).
Once you install ERPNext run -
$ bench get-app schools https://github.com/frappe/schools $ bench install-app schools
