+# GitProxy plugins & samples
+GitProxy supports extensibility in the form of plugins. These plugins are specified via [configuration](https://git-proxy.finos.org/docs/category/configuration) as NPM packages or JavaScript code on disk. For each plugin configured, GitProxy will attempt to load each package or file as a standard [Node module](https://nodejs.org/api/modules.html). Plugin authors will create instances of the extension classes exposed by GitProxy and use these objects to implement custom functionality.
+
+For detailed documentation, please refer to the [GitProxy development resources on the project's site](https://git-proxy.finos.org/docs/development/plugins)
+
+## Included plugins
+These plugins are maintained by the core GitProxy team. As a future roadmap item, organizations can choose to omit
+certain features of GitProxy by simply removing the dependency from a deployed version of the application.

 Please see the [sample plugin package included in the repo](https://github.com/finos/git-proxy/tree/main/plugins/git-proxy-plugin-samples) for details on how to structure your plugin package.
 
 If your plugin relies on custom state, it is recommended to create subclasses in the following manner:
 
 ```javascript
-import { PushActionPlugin } from "@finos/git-proxy/src/plugin";
+import { PushActionPlugin } from "@finos/git-proxy/src/plugin.js";
 
 class FooPlugin extends PushActionPlugin {

+    this.someProperty = 'Hello from the FooPlugin';
     // overwrite the parent's exec function which is executed as part of GitProxy's action chain.
     // use an arrow function if you require access to the instances's state (properties, methods, etc.)
     this.exec = async (req, action) => {
