This page covers only the core settings most users change first. For the complete configuration (citygen, assets_rp, traffic, map, user, scooter), see the :doc:`../additional_configuration/configuration` page.

Quick guidance
--------------

* Core settings: ``simworld`` is the main global block most users adjust first (e.g., seed, dt, UE manager path).
