Prevent execution of a cell

[whitead]

I would like to have a cell appear to help users install packages when launching the ipynb on binder or Google Colab. I do not want the cell to be executed when building because it contains code to install miniconda that is necessary on Google Colab. How do I achieve this? Thank you!!

I think what you after is jupyter-book/jupyter-book#833,
which is not addressed yet 😢
But obviously the more upvotes it gets, the more likely it will be 😉
