+### Configuration
+
 The YOC VIS.X adapter has the ability to work in different currencies. Currently, this adapter supports `EUR`, `USD`,
 `GBP`, `PLN`. Defaults to `EUR`. If your Ad Server uses `EUR`, you don't need any additional currency settings.
 If you would like to trade with VIS.X in a currency different from `EUR`, you should implement some additional settings.
