I did install projectile from melpa and now want to give it try. So I fiddled together this lines to get projectile mode.

 (use-package projectile
   :config
   (setq projectile-enable-caching t)
   (global-set-key (kbd "C-c p f") 'helm-projectile)
   (projectile-global-mode)
   ) ;; end of use-package

I also did "touch ~/.emacs.d/.projectile". Now when I open init.el I have projectile minor mode. Actually whati expected... But when I do

;;     (use-package projectile
;;       :config
;;       (setq projectile-enable-caching t)
;;       (global-set-key (kbd "C-c p f") 'helm-projectile)
;;       (projectile-global-mode)
;;       ) ;; end of use-package

and start a new emacs instance and open init.el it still has projectile minor mode enabled. Now I wonder why is that? Where may this be configured? There is no other version (other then the installed-by-me elpa version) of projectile installed on my hosting machine.
