 ========================================
 
-This project allows working with Jupyter notebooks in Google Cloud Storage.
+Jupyter Google Storage Contents Manager allows working with Jupyter notebooks directly in Google Cloud Storage.
 It aims to be a complete drop-in replacement for the stock filesystem
 [ContentsManager](http://jupyter-notebook.readthedocs.io/en/latest/extending/contents.html).
 Thus JGSCM is only compatible with a relatively modern IPython/Jupyter stack (version 4 and above).
