+### callback.lua
+
+These functions wrap the native callback handling of the selected framework (e.g., OX, QBCore, ESX) instead of implementing a standalone callback system, ensuring full compatibility.
+
+- **createCallback(callbackName, funct)**
+
+  - Registers a callback function with the appropriate framework.
+  - This function checks which framework is started (e.g., OX, QB, ESX) and registers the callback accordingly.
+  - It adapts the callback function to match the expected signature for the framework.
+  - **Example:**
+    ```lua
+    local table = { ["info"] = "HI" }
+    createCallback('myCallback', function(source, ...)
+        return table
+    end)
+
+    createCallback("callback:checkVehicleOwned", function(source, plate)
+        local result = isVehicleOwned(plate)
+        if result then
+            return true
+        else
+            return false
+        end
+    end)
+    ```
+
+- **triggerCallback(callbackName, ...)**
+
+  - Triggers a server callback and returns the result.
+  - This function uses the appropriate framework's method to call the server-side callback and awaits the result.
+  - **Example:**
+    ```lua
+    local result = triggerCallback('myCallback')
+    jsonPrint(result)
+
+    local result = triggerCallback("callback:checkVehicleOwned", plate)
+    print(result)
+    ```
