 The RTIC concept of a software task shares a lot with that of [hardware tasks](./hardware_tasks.md)
 with the core difference that a software task is not explicitly bound to a specific
-interrupt vector, but rather a “dispatcher” interrupt vector running
-at the same priority as the software task.

-Thus, software tasks are tasks which are not directly assigned to a specific interrupt vector.
+Thus, software tasks are tasks which are not *directly* bound to an interrupt vector.
 
-The `#[task]` attribute used on a function declare it as a software tasks.

-All software tasks at the same priority level shares an interrupt handler acting as a dispatcher.
-What differentiates software and hardware tasks are the dispatcher versus bound interrupt vector.

-The interrupt vectors used as dispatchers can not be used by hardware tasks.
+All software tasks at the same priority level share an interrupt handler bound to their dispatcher.

 Example: The `dispatchers =` argument needs to have at least 3 entries for an application using
 three different priorities for software tasks.
