 ## DruidJS — A JavaScript Library for Dimensionality Reduction.
 
+<a href="#"><img src="icon.svg" width=80 align="left" hspace="10" vspace="6"></a>
+
+DruidJS is a JavaScript library for dimensionality reduction. 
+With dimesionality reduction you can project high-dimensional data to a lower dimensionality while keeping method-specific properties of the data.
+DruidJS makes it easy to project a dataset with the implemented dimensionality reduction methods.
