Thanks for capturing this @leahhrlee since I forgot at the end that some people would run into some github issues when cloning the https:// links, so it would have been helpful at the break to let people know to create a github account and then (optionally) setup the token at that point...

...I think that is better to do later in the workshop if there is time to cover that material than to try to set all that up at the beginning if you end up running out of time and not using it.
