I have a question, that I can’t seem to find an answer for anywhere. I might be missing something obvious, but the best way to find out is to ask. So, when I re-open Rails, and I want to go back into an application, what do I enter in the terminal? I understand I use “rails new _______” when I am creating a new app, but what about when I just want to reopen an existing one? It seems like “cd appname” doesn’t work either. I’d appreciate any help you can offer in this regard.
