In this bot has been used variant with FSM. That means that you may use all the [Behaviour Builder with FSM](https://bookstack.inmo.dev/books/telegrambotapi/page/behaviour-builder-with-fsm) functionality. In case you wish to setup states repo, you should use the next code in the `setupDI` of your plugin:
```kotlin
single<StatesManager<State>> {
// setup your manager and return here
// Default is:
DefaultStatesManager(
InMemoryDefaultStatesManagerRepo()
)
}
```
Besides, you may setup handling errors lambda in the same function:
```kotlin
single<StateHandlingErrorHandler<State>> {
{ state, e ->
logger.eS(e) { "Unable to handle state $state" } // logging by default
null // you should return new state or null, default callback will return null
