How do you add the USPS plugin and install it in the Plugin Manager?
Hi, sorry the language wasn't clear.

When you download the module, either from the ZenCart Plugin Database or off the repository, you'll be given two choices: download the Encapsulated OR download the non-Encapsulated. Download the encapsulated version and there will be a Zip Folder that contains a folder named 'zc_plugin'. Extract the contents of that directory into the matching zc_plugin directory on your ZenCart installation. Visit your ZenCart Admin area and then visit Modules > Plugin Manager and there should be a new option named "USPS Shipping (w/REST API) for Zen Cart". Click on that row, then choose install. And if all worked well, you will see that it has been installed as well as a new option available under Modules > Shipping.
