I have a server with multiple ghost installations.
I need to modify the user signin pages in order to send a callback on successful login.
I think that the page that I need to modify is the following: https://github.com/TryGhost/Ghost-Admin/blob/0f7bf091f477e0187925c9b1936a683ab3b16b25/app/templates/signin.hbs
But I can’t find the page on disk.
I have no experience with npm and node.
