+`for` option is generally not needed as most plugins for specific file types
+usually don't have too much code in `plugin` directory. You might want to
+examine the output of `vim --startuptime` before applying the option.

 ### Post-update hooks
 
 There are some plugins that require extra steps after installation or update.
 In that case, use `do` option to describe the task to be performed.

 Plug 'Valloric/YouCompleteMe', { 'do': './install.sh' }
