Hey @Merynek, sorry for a late reply

transformToMobxFLow is not defined is a typescript error, you most likely missing the first step from this section to add type definitions

You may need to add a reference to this package's typescript definition file in order to declare the global transformToMobxFlow function:

/// <reference path="node_modules/ts-transform-async-to-mobx-flow/transformToMobxFlow.d.ts" />

It can be added to a global.d.ts file to access transformToMobxFlow in all the project files.
