-Sleep Manager
-=============
-
-The sleep manager is the middle-ware which provides means to control the sleep of
-an MCU by multiple software modules.
-
-The sleep manager uses publish-subscribe pattern to ask subscribers if they are
-ready to sleep and to notify them about preparation to sleep and waking up.
-
-If any of the subscribers is not ready to go to sleep, an MCU may stay in active
-mode. To let the sleep manager know that a software module is not ready to sleep,
-the parameter passed to callback must to set to false. No additional action is
-required from the software module to state that it is ready to go to sleep.
-Notification about waking up is delivered to all subscribers with information
-about wake-up reason.
-
-There are currently only two wake-up reasons: internal interrupt and external
-interrupt. It is up to the user to extend this list if required.
-
-Features
---------
-
-* Sleep control
-* Notifications:
-	* ready to sleep
-	* preparation to sleep
-	* waking up
-
-Dependencies
-------------
-
-* The sleep driver
-
-Limitations
------------
-
-* Only two wake-up reasons are supported by default

+============================
+The Timer driver (bare-bone)
+============================
+
+The Timer driver provides means for delayed and periodical function invocation.
+
+A timer task is a piece of code (function) executed at a specific time or periodically by the timer after the task has
+been added to the timers task queue. The execution delay or period is set in ticks, where one tick is defined as a
+configurable number of clock cycles in the hardware timer. Changing the number of clock cycles in a tick automatically
+changes execution delays and periods for all tasks in the timers task queue.
+
+A task has two operation modes, single-shot or repeating mode. In single-shot mode the task is removed from the task queue
+and then is executed once, in repeating mode the task reschedules itself automatically after it has executed based on
+the period set in the task configuration.
+In single-shot mode a task is removed from the task queue before its callback is invoked. It allows an application to
+reuse the memory of expired task in the callback.
+
+Each instance of the Timer driver supports infinite amount of timer tasks, only limited by the amount of RAM available.
+
+Features
+--------
+* Initialization and de-initialization
+* Starting and stopping
+* Timer tasks - periodical invocation of functions
+* Changing and obtaining of the period of a timer
+
+Applications
+------------
+* Delayed and periodical function execution for middle-ware stacks and applications.
+
+Dependencies
+------------
+* Each instance of the driver requires separate hardware timer capable of generating periodic interrupt.
+
+Concurrency
+-----------
+The Timer driver is an interrupt driven driver.This means that the interrupt that triggers a task may occur during
+the process of adding or removing a task via the driver's API. In such case the interrupt processing is postponed
+until the task adding or removing is complete.
+
+The task queue is not protected from the access by interrupts not used by the driver. Due to this
+it is not recommended to add or remove a task from such interrupts: in case if a higher priority interrupt supersedes
+the driver's interrupt, adding or removing a task may cause unpredictable behavior of the driver.
+
+Limitations
+-----------
+* The driver is designed to work outside of an operating system environment, the task queue is therefore processed in interrupt context which may delay execution of other interrupts.
+* If there are a lot of frequently called interrupts with the priority higher than the driver's one, it may cause delay for triggering of a task.
+
