People who want to try out org-mode but are familiar with vim shortcuts may want to check out spacemacs, it's an emacs distribution built to be useful for vim users. That way you can try out the real org-mode.
I see a lot of spacemacs users that seem rather confused on emacs basics. Makes me think you would be better of learning emacs, adding evil to the mix. Then using a starter kit if desired.
Where does one go to learn emacs basics?
Emacs has a built in tutorial. It is advertised on the welcome screen. You may find that it is a thoughtfully constructed and actually quite helpful. You won't be able to finish it in five minutes...
You learn Emacs basics within GNU Emacs itself https://www.gnu.org/s/emacs see in the menu Help, there is Tutorial, FAQ, Info pages, everything is self contained.
