+**Call for contributions:** 
+If you have developed and/or published new architectures using PyTorch and intend to make them opensource, 
+consider include them as part of SimulAI, which works as an unified repository for scientific machine learning models, continuously tested and maintained. 
+SimulAI was already packaged under a friendly license (Apache) and it can be used to more easily share state of the art models whithin the scientific community.
