+This section overviews machine learning frameworks and libraries available on the clusters.
 
 ## TensorFlow
 
-Load TensorFlow module:
+TensorFlow is an end-to-end open source platform for machine learning. It has a comprehensive, flexible ecosystem of tools, libraries, and community resources that lets researchers push the state-of-the-art in ML and developers easily build and deploy ML powered applications. For more information, see the [official website][a].
 
-```console
-$ ml Tensorflow
-```
+For the list of available versions, see the [TensorFlow][1] section:
+
+## Theano
+
+Theano is a Python library that allows you to define, optimize, and evaluate mathematical expressions involving multi-dimensional arrays efficiently. It can use GPUs and perform efficient symbolic differentiation. For more information, see the [official webpage][b] (GitHub).
 
-Test module:
+For the list of available versions, type:
 
 ```console
-$ ml Tensorflow
+$ ml av Theano
 ```
 
-Read more about available versions at the [TensorFlow page][1].

-## Theano
+## Keras
 
-Read more about [available versions][2].
+Keras is an API designed for human beings, not machines. Keras follows best practices for reducing cognitive load: it offers consistent & simple APIs, it minimizes the number of user actions required for common use cases, and it provides clear & actionable error messages. It also has extensive documentation and developer guides. For more information, see the [official website][c].
