+ClassyVision |classyvision|
+---------------------------
+
+Classy Vision is a new end-to-end, PyTorch-based framework for large-scale training of state-of-the-art image and video classification models. The library features a modular, flexible design that allows anyone to train machine learning models on top of PyTorch using very simple abstractions. 
 
 
-Horovod
--------
+[`Link to integration <https://classyvision.ai/tutorials/ray_aws>`__]
+
+Dask |dask|
+-----------
+
+Dask provides advanced parallelism for analytics, enabling performance at scale for the tools you love. Dask uses existing Python APIs and data structures to make it easy to switch between Numpy, Pandas, Scikit-learn to their Dask-powered equivalents.
+
+[`Link to integration <dask-on-ray>`__]
+
+Flambe |flambe|
+---------------
+
+Flambé is a machine learning experimentation framework built to accelerate the entire research life cycle. Flambé’s main objective is to provide a unified interface for prototyping models, running experiments containing complex pipelines, monitoring those experiments in real-time, reporting results, and deploying a final model for inference.
+
+Github: `https://github.com/asappresearch/flambe <https://github.com/asappresearch/flambe>`_
+
+MARS |mars|
+-----------
+
+Mars is a tensor-based unified framework for large-scale data computation which scales Numpy, Pandas and Scikit-learn. Mars can scale in to a single machine, and scale out to a cluster with thousands of machines.
+
+
+[`Link to integration <mars-on-ray>`__]
+
+Modin |modin|
+-------------
+
+Scale your pandas workflows by changing one line of code. Modin transparently distributes the data and computation so that all you need to do is continue using the pandas API as you were before installing Modin. 
+
