+## Using custom modules in 'execute python' in shuffle-tools
+
+If you want to install a custom module like pandas (although, 'execute python' isn't made for heavy processing. We recommend making a custom python app for it).

+- Copy the Shuffle Tools app and add the libraries you want to it! Library configuration is over here: https://github.com/Shuffle/python-apps/blob/master/shuffle-tools/1.2.0/requirements.txt
