+--- **AceTimer-3.0** provides a central facility for registering timers.
+-- AceTimer supports one-shot timers and repeating timers. All timers are stored in an efficient
+-- data structure that allows easy dispatching and fast rescheduling. Timers can be registered
+-- or canceled at any time, even from within a running timer, without conflict or large overhead.\\
+-- AceTimer is currently limited to firing timers at a frequency of 0.01s. This constant may change
+-- in the future, but for now it's required as animations with lower frequencies are buggy.
+--
+-- All `:Schedule` functions will return a handle to the current timer, which you will need to store if you
+-- need to cancel the timer you just registered.
+--
+-- **AceTimer-3.0** can be embeded into your addon, either explicitly by calling AceTimer:Embed(MyAddon) or by
+-- specifying it as an embeded library in your AceAddon. All functions will be available on your addon object
+-- and can be accessed directly, without having to explicitly call AceTimer itself.\\
+-- It is recommended to embed AceTimer, otherwise you'll have to specify a custom `self` on all calls you
+-- make into AceTimer.
