How do I add a comment in Vim's configuration files, like .vimrc?

A double quote to the left of the text you want to comment.

Example: " this is how a comment looks like in ~/.vimrc

To be clear: Do not include a closing double quote. (See comment from Arslan Ali below.)

"This is a comment in vimrc. It does not have a closing quote

Same as above. Use double quote to start the comment and without the closing quote.

Example:

set cul "Highlight current line

You can add comments in Vim's configuration file by either:

" brief description of the command 

or:

"" commented command
