+This repository contains a list of internal names for Autodesk Inventor. Each category is broken down into its own namesspace (e.g. Ribbon, PropertySets, iProperties, etc.)
 
-## Ribbon Internal Names
+## Ribbon Components

+ User Interface Components. The internal names are used to identify the user interface components in the Inventor API. The internal names are used in the `Ribbon`, `RibbonTab`, and `RibbonPanel` classes to identify the user interface components.
+
+### Ribbon Internal Names
 
 Ribbon internal names are found in `InventorRibbons`. 
 
-## RibbonTab Internal Names
+### RibbonTab Internal Names
 
 RibbonTab internal names are found in `PartRibbonTabs`, `AssemblyRibbonTabs`, and `DrawingRibbonTabs`.
 
-## RibbonPanel Internal Names
+### RibbonPanel Internal Names
 
 RibbonPanel internal names are found in `PartRibbonPanels`, `AssemblyRibbonPanels`, and `DrawingRibbonPanels`. Panel names are broken down into their respective tabs.
 
-## Example:
+### Example:
 ```csharp
 var drawingRibbon = inventorApplication.UserInterfaceManager.Ribbons[InventorRibbons.Drawing];
 
 var placeViewsTab = drawingRibbon.RibbonTabs[DrawingRibbonTabs.PlaceViews];
 
 var createPlaceViewsPanel = placeViewsTab.RibbonPanels[DrawingRibbonPanels.PlaceViews.Create];
