nopCommerce API and Android studio

Hello. Help us integrate the nopcommerce API into the Android Studio. Download the API itself from Git. And then a dead end

Android Studio provides an IDE for building apps Android devices.
The API plugin for nopCommerce provides a RESTful API for managing resources in nopCommerce.

You need to write code in your Android application that will make RESTful requests to the API.

I worked with Google API, so there was a key. And now I only have a zip archive. I can't find any information for working with nopCommerce. since all forums are English-speaking,but there are no Russian-speaking ones( Maybe there is a link to the guide ?

If you are not at all familiar with nopCommerce, then you should read the developer documentation.  When you understand the basics of nopCommerce architecture / domains, then look at the code of the API plugin to understand the features it has.
