-### Plugin directory
-
-If you omit the path argument to `plug#begin()`, plugins are installed in
-`plugged` directory under the first path in `runtimepath` at the point when
-`plug#begin()` is called. This is usually `~/.vim/plugged` (or
-`$HOME/vimfiles/plugged` on Windows) given that you didn't touch runtimepath
-before the call.
