 The repository contains several ingredients:
 *   `installer.js` - combination of postinstall scripts for adding or removing webpack configurations and necessary dependecies when installing the plugin.
-*    `prepublish` - [Webpack config](https://webpack.js.org/concepts/configuration/) snippets used for generating webpack configuration templates. The latter are generated with the npm's `prepublishOnly` script. **If you want to modify the distributed webpack configurations - that's the right place to do it.**
-*   `templates` - webpack config templates for different types of projects - NativeScript with JavaScript, NativeScript with TypeScript and NativeScript Angular projects.
-*   `plugins` - several [Webpack plugins](https://webpack.js.org/concepts/plugins/) necessary for bundling NativeScript applications.
-*   `snapshot/android` - tools used with the `NativeScriptSnapshot` plugin for generating V8 Heap Snapshots.
-*   `nativescript-target` - configuration of a [Webpack deployment target](https://webpack.js.org/concepts/targets/) for building NativeScript applications.
-*   `bin` - helper node/npm scripts for projects using the plugin.
-*   `bin/ns-bundle` - node script used for bundling the project with Webpack and building the native Android/iOS application with NativeScript CLI.

You can execute each app's tests by navigating to its directory and running `npm run e2e -- --runType nameOfRuntype`. For more information on runTypes, check out the [nativescript-dev-appium](https://github.com/NativeScript/nativescript-dev-appium#custom-appium-capabilities) plugin.

 ## Setup
