Rails Broadway project I need help understanding step 7

Link to the page of the project I need help understanding

If you follow the link, step 7 I’m having trouble understanding. It says: “In your Rails project, create app/views/pages/home.html.erb” The center panel of the screen is divided with the code editor on top and terminal on the bottom. Am I supposed to be creating this file in the terminal? (I did try and for some reason it didn;t work.) Or adding a file in the code editor? In either case, the next part of this step is: “Then, copy and paste the contents of the root home.html.erb into your newly-created file. Then, similarly, copy and paste the contents of the root pages.css into app/assets/stylesheets/pages.css.scss.” I just added a file in the code editor, copied the contents of home.html.erb but cannot figure out how to paste it into the new file. Can someone explain this step to me?
