 # What is `level`?
 `level` is a tool for reskit that converts [Tiled Map Editor](https://www.mapeditor.org/) tilesets and maps to a binary format accessible to C or assembly language engines. It distinguishes itself from other available homebrew tools by offering support for Tiled's native tmx/tsx XML formats, and user-specified event objects (e.g. "drop enemy", "open door") that your custom engine can read and apply.
+
+# Events
+By adding an object layer and object in Tiled, and adding the property `reskit-event`, you can define an event triggered in certain scenarios depending on additional `reskit-*` properties.
+
+| Object Property          | Description                                                                                                                                         |

+| reskit-event                | String. Defines an event type to use (see Event Types) |
+| reskit-character          | String. Target character defined for a particular event type |
