 qdatalib API Documentation
 **************************************************
-
+QDataLib is a library of wrappers around some of the most useful ”data”-functions in QCoDeS. 
+The Idea of QDataLib is to keep track of your data files using a MongoDB database, 
+and ease the export to other file formats than SQLite.
 
 This page documents the qdatalib API.
