Hello,

I am trying to run my Github repository via binder to be able to share my slicer notebook files (.ipynb) with other people. I am able to create the binder repository but when I open up a .ipynb file the default kernel is set to Python 3 and the dropdown menu does not show the Slicer 4.11 kernel for me to select as for example when I open a .ipynb file in the tutorial binder repository( [https://hub.gke.mybinder.org/user/slicer-slicernotebooks-n86z0bik/tree](https://hub.gke.mybinder.org/user/slicer-slicernotebooks-n86z0bik/tree)). Do I have to introduce some sort of requirement in a txt file or define that I want the Slicer kernel to be used?

github link I am trying to put on binder: [https://github.com/allihuwa/Content-Production-for-Improving-Cancer-Treatment-Worklflow](https://github.com/allihuwa/Content-Production-for-Improving-Cancer-Treatment-Worklflow)

Thank you!

To have a Slicer kernel, all you need is two small text files in the your repository’s root (`Dockerfile` and `start`) as it is one in this repository: [https://github.com/Slicer/SlicerNotebooks](https://github.com/Slicer/SlicerNotebooks).
