osx - How to switch to edit mode of vi on mac terminal -

-

i new mac, trying edit .gitignore file macbook terminal, type 

 vi .gitignore

it opens file not letting me switch edit mode. how vi switches mode on mac ?

on mac can more correctly type vim (vi improved) instead :)

same everywhere, i switches "insert" mode , esc switches command mode.

a learning resource vim included in mac. type vimtutor , teach how use vim effectively.

another editing option on mac nano command line text editor easier familiar textedit/notepad.
