+##FAQ
+### What does `editing : ToDo.from( '^props.todos' )` from `todolist.jsx` mean?
+Shortly, this reference is a path relative to `this`. Symbol `^` means that we reference something from the upper level. Methods `.from` and `.subsetOf` are serialized as `id` and array of `id` from the model. You work with them same as with simple model or collection. To get this `id` we need a reference to the whole model. 
+
+For instance, `someAttr : Model.from( 'items' )` means that in `someAttr` you have one of the models from collection `item`. Common use case: you have a list and you need a reference for selected item.
