Add it to your server
In your server's .ini file (servertest.ini by default), add these to the existing WorkshopItems= and Mods= lines, separated by a semicolon (;).
WorkshopItems=3805285544;3825407687
Mods=PZ_Optimization;PZOptimizationTC
These lines include the mod it requires, as its Steam page declares it:
| Workshop item | Subscribers | Declared in |
|---|---|---|
