 Tasks can
 
-* Be spawned (now or in the future)
-* Receive messages (message passing)
-* Prioritized allowing preemptive multitasking
+* Be spawned (now or in the future, also by themselves)
+* Receive messages (passing messages between tasks)
+* Be prioritized, allowing preemptive multitasking
 * Optionally bind to a hardware interrupt
 
 RTIC makes a distinction between “software tasks” and “hardware tasks”.
-Hardware tasks are tasks that are bound to a specific interrupt vector in the MCU while software tasks are not.
 
-This means that if a hardware task is bound to an UART RX interrupt the task will run every
-time this interrupt triggers, usually when a character is received.
+*Hardware tasks* are tasks that are bound to a specific interrupt vector in the MCU while software tasks are not.
+
+This means that if a hardware task is bound to, lets say, a UART RX interrupt, the task will be run every
+time that interrupt triggers, usually when a character is received.
+
+*Software tasks* are explicitly spawned in a task, either immediately or using the Monotonic timer mechanism. 
 
 In the coming pages we will explore both tasks and the different options available.
