## Purpose and preparation


Egosoft lists Celludriel's X4 Universe Generator as WIP, intended to accelerate custom-universe creation. Configuration format and supported game version belong to a specific release; current compatibility is not claimed here.



## First exercise


1. Read release instructions and prepare matching game data.
2. Start with a minimal set of sectors and one clear connection.
3. Generate into a separate folder; inspect outputs and unique macro names.
4. Check galaxy/cluster/sector/zone references and connections.
5. Use a test extension and a separate test start.



## Expected result


The output is a set of map files. Check sector accessibility and a concrete connection, rather than only a visual layout.



## Checks and limits


Read [map structure](wiki:galaxy-structure) and [9.00 resource areas](wiki:resource-areas) before generation: an older region format is not automatically current.



Current button labels are unverified because the author's thread requires an access check. An existing save may not adopt world changes like a new start. Generation alone does not validate economy or missions.
