Reference

The pages in this group are lookup tables rather than guides. They are the source of truth for the values they list; the guides in Configuration and Deployment link here instead of repeating them.

Page	Use it when
Environment variables	You are filling in a .env file or wondering what a variable does and what its default is.
Background jobs	You want to know what runs on a schedule, what a queue name in the logs means, or why something is delayed.
CLI	You need to run a maintenance command by hand.
Ports and services	You are opening firewall rules or reading docker-compose.yml.
Troubleshooting	The server refuses to start, sync does nothing, or emails never arrive.
