# Overview

All tunable settings live in [`shared/config.lua`](https://github.com/KOJA/koja-carmarket/blob/main/shared/config.lua).

Use this page as a quick map before you change individual sections.

## At a glance

```lua title="shared/config.lua"
Config.Debug = false                       -- toggle debug prints
Config.Locale = 'en'                       -- UI language (en | pl | de | es | fr | pt | ro | ru | sk | zh)

Config.Database = { AutoCreateTable = true }

Config.Interaction = 'ox_target'           -- or nil for draw-text prompts
Config.InventoryMenuSystem = 'ox_lib'      -- menus driver
Config.ZoneSpawnRadiusDefault = 50         -- vehicle spawn radius (m)
```

## Toggling debug

```lua title="shared/config.lua"
Config.Debug = true
```


When enabled, every callback logs its inputs and decisions to console via `KOJA.Shared.KojaCarmarketDebug`. Leave this **off** in production — it's noisy.

:::hint{type="warning"}
Don't ship with `Config.Debug = true`. It exposes player identifiers and listing data in your console logs.

## Changing the UI language

```lua
Config.Locale = 'pl'
```

Available codes: `en`, `pl`, `de`, `es`, `fr`, `pt`, `ro`, `ru`, `sk`, `zh`.

Missing translation keys fall back to the English defaults — no broken UI keys will leak through.
