 # Module: Dragon Kills
 [![Build Status](https://travis-ci.org/lotgd/module-dragon-kills.svg?branch=master)](https://travis-ci.org/lotgd/module-dragon-kills)
 
-A simple way to track dragon kills in your realm. Stores the number of "DK's" on the Character model in `$c->getProperty('lotgd/dragon-kills/dk')`
-and also keeps an entry for each DK in a table.
+Adds the green dragon to the forest to challenge if the character reached level 15. Additionaly, it 
+keeps track of the dragon kills in your realm and stores the kill count on the character model.
 
-## Events
-`e/lotgd/dragon-kills/kill`: This module responds to this event and stores the dragon kill in the database and increments the count on the Character model.
+## API
+### Events
+- `e/lotgd/dragon-kills/kill` (`Module::DragonKilledEvent`)\
+This module publishes this event if a dragon has been slain. It can be used to reset the character and
+strip him from his achievements.
 
-## Models
-`LotGD\DragonKills\Models\DragonKill`: Database model for each DK event, storing the Character, when it occurred in game time and when it occurred in real time.
