To answer your question @Khang_Le, version 13 is not officially released yet so it is not recommended to install it in production. But if you want to try it out as a test setup, while doing bench init you can mention the version number as version-13-beta or develop.
GitHub - frappe/bench: CLI to manage Multi-tenant deployments for Frappe apps refer this link for a more detailed setup instructions. Docker is also a good way to setup your test/dev environment quickly
