 Below is a basic example of how to use the SDK:
 
-````go
-import "git.anthrove.art/Anthrove/plug-sdk/v3/pkg/plug"
+### proposed Plug structure
 
-// Define what Source this Plug is used for
-source := models.Source{
-    DisplayName: "e621",
-    Domain:      "e621.net",
-    Icon:        "e621.net/icon.png",
