> - So, how did you learn Vim? I heard there's quite a learning curve.
You can go through the interactive vimtutor.
Type :help tutor
Or you can just type :help and find the link to the vimtutor. If you are using gVim, then it should be one of the menu items ( maybe under help? ).
My suggestion is to just search for basic vim cheat sheet if you are getting started. There are also youtube tutorials online. Sometimes watching someone work with vim can help you get over the hump.
> - I just open it, but I couldn't figure out how to quit.
:q to quit.
:q! to quit without saving.
Remember to hit ESC to get back to the normal mode first if you are in other modes.
When you are comfortable with Vim then you can go on to some of the advanced vim topics. Also, in the beginning you might have to ddg/google/etc a bit. Good luck.
