If you want to update current Revolution Slider version you have 2 ways to do it:

1. Go to Revolution Slider section which is in main wp dashboard section on the left side. Then click on "Update Plugin" button in the right bottom corner, go to theme-name\functions\plugins folder and select revslider.zip file and just upload it. That`s it.


2. You can do it via FTP. Just log in into your FTP server and go to wp-content/plugins/revslider/ folder. Unpack files from revslider.zip file which has been described in point 1 and replace files from unpacked folder into your FTP to wp-content/plugins/revslider/ folder

Revolution Slider is external plugin which is included into theme because for each product we purchase "Extended license" and that's why we are able to include it into them.
