A framework is "supported" when there is a framework :term:`bridge` that can be 
cloned from one of our GitHub repos and built to connect to nGraph device backends, 
all the while maintaining the framework's programmatic or user interface. Bridges 
currently exist for the TensorFlow\* and MXNet\* frameworks.

    :abbr:`Just-in-Time (JiT)` Compiling for computation

Once connected via the bridge, the framework can then run and train a deep 
learning model with various workloads on various backends using nGraph Compiler 
as an optimizing compiler available through the framework.  

While a :abbr:`Deep Learning (DL)` :term:`framework` is ultimately meant for 
end use by data scientists, or for deployment in cloud container environments, 
nGraph Core ops and the nGraph C++ Library are designed for framework builders 
themselves. We invite anyone working on new and novel frameworks or neural 
network designs to explore our highly-modularized stack of components that can 
be implemented or integrated in virtually limitless ways.

Please read the articles in this section if you are considering incorporating 
components from the nGraph Compiler stack in your framework or neural network 
design. Articles here are also useful if you are working on something 
built-from-scratch, or on an existing framework that is less widely-supported 
than the popular frameworks like TensorFlow and PyTorch.
