I\'m in the process of learning github on mac (command-line) and whenever I do git pull origin master i get this
# Please enter a commit message
The editor looks like to be vim according to your descriptions. This console is simply telling you to write some message for the commit you want to make, and it is compulsory as it does.
Just type i and you'll go in the -- INTER -- mode, now you can write your comments.
After you have done writing, press esc key in your keyboard and you'll go to command mode. (see on the bottom of the console)
Now save changes by writing :w followed by pressing enter key
:q followed by pressing enter key
