On pages like http://docs.cs50.net/problems/fifteen/fifteen.html when there is a $
preceding a command, it would be helpful to format it in a way as to not copy paste the $
.
You could consider an approach like Digital Ocean uses in their tutorials:

Alternatively, we could just remove the dollar signs. Other places in the docs are already this way. (See http://docs.cs50.net/2017/x/psets/5/pset5.html for examples).
