 - `cond`: A transition condition that evaluates to a Bool, such as `ticksInState() >= 2`.
 - `immediate`: If `true`, the transition will fire at the same tick as it becomes true, if `false`, the actions of the state are evaluated first, and the transition fires during the next tick.
 - `reset`: If true, the destination state `to` is reset to its initial condition when the transition fires.
-- `synchronize`: If true, the transition will only fire if all sub-state machines in the destination state are in their final (terminal) state. A final state is one that has no outgoing transitions.
+- `synchronize`: If true, the transition will only fire if all sub-state machines in the source state are in their final (terminal) state. A final state is one that has no outgoing transitions.
 - `priority`: If a state has more than one outgoing transition, all outgoing transitions must have a unique priority. The transitions are evaluated in priority order, i.e., the transition with priority 1 is evaluated first.
