+## Commander
+
+### Quick Introduction
+
+**Commander** introduces a new event system to the data pack format.
+
+Each file placed in `commander/events` represents an event subscription. Commander mirrors some fabric events under the `commander` namespace. e.g. `server_tick/start`
+
+```json
+{
+  "event": "namespace:event", //the event this file subscribes to.
+  "parameters": null, //optional parameters block
+  "commands": [
+    {
+      "type": "namespace:command", //command type
+      "condition": { //optional conditions block. Uses the vanilla predicates system
+        "condition": "minecraft:random_chance",
+        "chance": 0.5
+      },
+      "parameter": null, //misc command parameters
+      "parameter_2": 2
+    }
+  ]
+}
+```
+
+`parameters` is a block of addition subscription info. Can be omitted if the event does not expect any parameters.
+
+`commands` block defines actions the event will perform when invoked. Commands don't always interact with the game world, some commands are purely logical (`commander:random`), some are service commands (`commander:cancel`).
