 In progress three.js implementation of the [3D Tiles format](https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/specification/).
 
-## Unsupported Features
+The renderer supports a limited subset of the spec for the moment. See [Issue #15](https://github.com/NASA-AMMOS/3DTilesRendererJS/issues/15) for information on which features are not yet implemented. 
 
-### Model Formats
+# Use
 
-- [i3dm format](https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/specification/TileFormats/Instanced3DModel/README.md)
-- [pnts format](https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/specification/TileFormats/PointCloud/README.md)
-- [cmt format](https://github.com/AnalyticalGraphicsInc/3d-tiles/blob/master/specification/TileFormats/Composite/README.md)
+```js
+// TODO
+```
 
-### B3DM Features
+# API
 
-- Per batched feature metadata extraction
-- Individual feature access, selection, and updates
-- Individual feature transform and position
+## ThreeTilesRenderer
 
-### Tileset Features
+### .group
 
-- [Region](https://github.com/AnalyticalGraphicsInc/3d-tiles/tree/master/specification#region) bounding volume support
