| Asa@0 | 1 --- **AceAddon-3.0** provides a template for creating addon objects. | 
| Asa@0 | 2 -- It'll provide you with a set of callback functions that allow you to simplify the loading | 
| Asa@0 | 3 -- process of your addon.\\ | 
| Asa@0 | 4 -- Callbacks provided are:\\ | 
| Asa@0 | 5 -- * **OnInitialize**, which is called directly after the addon is fully loaded. | 
| Asa@0 | 6 -- * **OnEnable** which gets called during the PLAYER_LOGIN event, when most of the data provided by the game is already present. |
