I have a few Jupyter Notebooks in a Github Repository that are often accessed through mybinder.org via link from people who are new to Python and don’t have Jupyter Notebooks or any IDE for Python installed on their systems (yet). I thought it would be great if there was some kind of text or message added to the environment when people start it. So currently mybinder.org get’s the link to my repo on Github and when the binder/jupyter-notebooks environments starts I see the list of files on my github in the sidebar to the left, and the Launcher in the main body. What I’d want is to simply add some text/html to the launcher to say something like “Welcome to this binder, you can find all the date in this github (link), have fun!” and then have the tiles where you can select a new Notebook etc. I’d also be happy with an alternative solution, as long as it’s visible to uers.
