I'm looking at this link, which referencing this link as the first step.
My question would be: can I do the first step from the Terminal (command prompt)?
Thank you.
You can create an (empty) project using git init
:
mureinuj@computer ~/src/git $ git init myproject
Initialized empty Git repository in /home/mureinik/src/git/myproject/.git/
From there on, it's just pushing the (now existing) project into GitHub, as described by the link you provided.
