 1. Implement [math](multik-api/src/main/kotlin/org/jetbrains/kotlinx/multik/api/Math.kt) and [linalg](multik-api/src/main/kotlin/org/jetbrains/kotlinx/multik/api/LinAlg.kt) interfaces.
 2. Create your own engine successor from [Engine](multik-api/src/main/kotlin/org/jetbrains/kotlinx/multik/api/Engine.kt), for example - [JvmEngine](multik-jvm/src/main/kotlin/org/jetbrains/kotlinx/multik/jvm/JvmEngine.kt).
