+
+## 1. Overview
+
+The ACE3 Modules framework provides a module base class that lets you initialize modules in unscheduled execution space. This lets us ensure that modules placed in the editor run when they are supposed to.
+
+## 2. How it Works
+
+It provides a nearly identical interface too the [Arma 3 modules framework](https://community.bistudio.com/wiki/Arma_3_Module_Framework){:target="_blank"}. The biggest issue with the Arma 3 modules is that they run in scheduled space. This means that there is no guarantee when a module initializes.
+
+To solve this, we have build a framework on top of the Arma 3 modules framework. For the Arma 3 framework, your modules inherit from `Module_F`. To make use of the ACE3 Module framework, you will need to inherit from `ACE_Module`.
+
+## 3. Limitations
+
+Because we at the moment do not need all the functionality from the Arma 3 Modules framework within ACE, we officially only support modules that execute once (on mission start). Our prime use case are settings modules.
+
+Other use cases may work, however are not supported by us. Use at your own risk.
+
+## 4. Examples
+
+```cpp
+class CfgVehicles {
+    class ACE_Module;
+    class ACE_bananaModule: ACE_Module {
+        scope = 2;
+        displayName = "Spawn Banana";
+        category = "ACE";
+        function = "ace_fnc_bananaModuleInit";
+        functionPriority = 10;
+        isGlobal = 0;
+        isTriggerActivated = 0;
+        isDisposable = 0;
+        author = "Monkey123";
+    };
+};
+```
