 # Tutorials
 
-These tutorials introduce a few fundamental concepts in deep learning and how to implement them in _MXNet_. The _Basics_ section contains tutorials on manipulating arrays, building networks, loading/preprocessing data, etc. The _Training and Inference_ section talks about implementing Linear Regression, training a Handwritten digit classifier using MLP and CNN, running inferences using a pre-trained model, and lastly, efficiently training a large scale image classifier.

 ## Gluon
 
 Gluon is the high-level interface for MXNet. It is more intuitive and easier to use than the lower level interface.
 Gluon supports dynamic (define-by-run) graphs with JIT-compilation to achieve both flexibility and efficiency.
-This is a selected subset of Gluon tutorials. For the comprehensive tutorial on Gluon,
