C-x g doesn't always open magit

Question

When I start emacs and press C-x g, it says: "C-x g is undefined". I can open a file belonging to the repository, and it still doesn't work. I need to start it manually (?) (C-x magit-status). And it's only after that that the keybinding starts working. But it still doesn't work in the *GNU Emacs* buffer, and in Dired. What's the supposed workflow? Should I add something to the config?

My current ~/.emacs:

(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(package-selected-packages (quote (magit))))
(custom-set-faces
 ;; custom-set-faces was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 )

Magit tries to establish that binding automatically using global-magit-file-mode. However that does not actually work. It's a known bug. You didn't mention this mode so I don't know whether you are aware that this mode is supposed to define that binding. But since it doesn't actually work that doesn't matter.

You have to define the binding yourself by adding something like this to your init file.

(define-key global-map (kbd "C-c g") 'magit-status)
