Visual Composer has a very simple and intuitive interface, but before getting started, you may find it useful to get accustomed with its documentation.
In Elessi, we also create some new elements that will help you a lot to build your website easier.
If you have Visual Composer with a theme which you have purchased from ThemeForest, then you don't need to activate it. We purchased the extend license for this plugin. The update option is for users who have purchased this plugin individually.
