... the documentation on how to get started today. Plugins for Xamarin are community-built NuGet and Components that add cross-platform functionality or abstract platform-specific functionality to a common API. These are both completely cross-platform and extremely small (i.e., they do 1 or 2 things really well with minimal-to-no dependencies). The Plugin API can be accessed on each platform, however, you will most likely only use the common API in a .NET Standard project.
