+1. `object` The object in use
+
+### Usage
+
+```lua
+local mainFrame = basalt.createFrame()
+
+-- Add some child objects to the frame
+mainFrame:addLabel("label1", "Hello", 5, 5)
+mainFrame:addButton("button1", "Click Me", 5, 10)
+
+-- Remove all child objects from the frame
+mainFrame:removeChildren()
+```
