Opencart ThemeForest Templates

Hi. New here. Sorry stupid questions. I’ve been looking for ThemeForest OpenCart templates and got to Envato. The preview drove me to Who’s actually selling, please, ThemeForest, Envato or Mahardi? Perhaps it’s not my problem, but I need to know who will provide support for my purchase. Next, will I get a full installation package with the template embeded, or I have to install the standard OpenCart package and then install the template as an extension? Finally, what other extensions, modules, plugins are required for the package and the template to be fully functional for ecommerce use?

Hi you can purchase themeforest opencart template you will get installation guide with documentation.
You will received 6 month item support.
