 Litemol2glTF exports scenes from LiteMol to the glTF format.
 
+The project uses the [LiteMol](https://litemol.org) viewer to download, visualize 
+and adjust the look of a molecule which is provided by a PDB ID. 
+
+The visualization is provided by a modified LiteMol's CustomControles [example](https://github.com/dsehnal/LiteMol/tree/master/examples).
+
+
+The Export functionality
+is provided by a modified version of [GLTFExporter](https://threejs.org/docs/#examples/exporters/GLTFExporter) 
+from the [three.js](http://threejs.org) project.  litemol2gltf uses a modified exporter because
+LiteMol is built over a modified old release of three.js which is not compatible with the current
+GLTFExporter.
