# Fabric-Kotlin MDK This is an example of using Cobblemon with Fabric and Kotlin. This mirrors the logic in the Java version of the MDK. ## Notice when writing mixins When writing mixins, you should write these in Java and not in Kotlin due to a lack of support for Kotlin. More information about this can be read on this [Sponge Issue](https://github.com/SpongePowered/Mixin/issues/245)
