+## 1. Requirements
+
+Object must inherit from `ThingX` or any of its sub-classes.
+
+Object must have Extended Event Handler (XEH) enabled (this is not the case for the majority of vanilla objects in `ThingX` class), configuration entry on how to do that is shown below.
+
+
+## 2. Config Values
+
+```cpp
+class CfgVehicles {
+    class MyChair {
+        acex_sitting_canSit = 1;  // Enable sitting
+        acex_sitting_sitDirection = 180;  // Direction relative to object
+        acex_sitting_sitPosition[] = {0, -0.1, -0.45};  // Position relative to object (may behave weird with certain objects)
+        XEH_ENABLED;  // Enable XEH (only necessary if XEH is not yet enabled for this class or the one this inherits from)
+    };
+};
+```
