This will launch an editor for editing empty files.
No matter how long you wait here, nothing happens.
(It's just the editor launching and waiting for you to edit.)
Using the launched editor, as described on the referenced site
Do "Write the following contents in the Dockerfile" and save the file.
If you don't know how to use vi, please check it yourself.
