+### Quick Statrt on how to us ns3-ai - [a_plus_b](https://github.com/hust-diangroup/ns3-ai/tree/master/examples/a_plus_b)
 This example show how you can use ns3-ai by a very simple case that you transfer the data from ns-3 to python side and calculate a + b in the python to put back the results. Please check the README in it for more details.

 This original work is done based on [5G NR](https://5g-lena.cttc.es/) branch in ns-3. We made some changes to make it also run in LTE codebase in ns-3 mainline. We didn't reproduce all the experiments on LTE, and the results used in this document are based on NR work.
