+# Puppeteer Angular Schematic
+
+Adds Puppeteer-based e2e tests to your Angular project.
+
+## Getting started
+
+Run the command below in an Angular CLI app directory and follow the prompts.
+
+> Note this will add the schematic as a dependency to your project.
+
+```bash
+ng add @puppeteer/ng-schematics
+```
+
+Or you can use the same command followed by the [options](#options) below.
+
+Currently, this schematic supports the following test frameworks:
+
+- [**Jasmine**](https://jasmine.github.io/)
+- [**Jest**](https://jestjs.io/)
+- [**Mocha**](https://mochajs.org/)
+- [**Node Test Runner** _(Experimental)_](https://nodejs.org/api/test.html)
+
+With the schematics installed you can run E2E tests:
+
+```bash
+ng e2e
+```
+
+### Options
+
+When adding schematics to your project you can to provide following options:
+
+| Option               | Description                                                                                                             | Value                                      | Required |
+| -------------------- | ----------------------------------------------------------------------------------------------------------------------- | ------------------------------------------ | -------- |
+| `--isDefaultTester`  | When true, replaces default `ng e2e` command.                                                                           | `boolean`                                  | `true`   |
+| `--exportConfig`     | When true, creates an empty [Puppeteer configuration](https://pptr.dev/guides/configuration) file. (`.puppeteerrc.cjs`) | `boolean`                                  | `true`   |
+| `--testingFramework` | The testing framework to install along side Puppeteer.                                                                  | `"jasmine"`, `"jest"`, `"mocha"`, `"node"` | `true`   |
+| `--port`             | The port to spawn server for E2E. If default is used `ng serve` and `ng e2e` will not run side-by-side.                 | `number`                                   | `4200`   |
+
+## Creating a single test file
+
+Puppeteer Angular Schematic exposes a method to create a single test file.
+
+```bash
+ng generate @puppeteer/ng-schematics:test "<TestName>"
+```
+
+### Running test server and dev server at the same time
+
+By default the E2E test will run the app on the same port as `ng start`.
+To avoid this you can specify the port the an the `angular.json`
+Update either `e2e` or `puppeteer` (depending on the initial setup) to:
+
+```json
+{
+  "e2e": {
+    "builder": "@puppeteer/ng-schematics:puppeteer",
+    "options": {
+      "commands": [...],
+      "devServerTarget": "sandbox:serve",
+      "testingFramework": "<TestingFramework>",
+      "port": 8080
+    },
+    ...
+}
+```
+
+Now update the E2E test file `utils.ts` baseUrl to:
+
+```ts
+const baseUrl = 'http://localhost:8080';
+```
+
+## Contributing
+
+Check out our [contributing guide](https://pptr.dev/contributing) to get an overview of what you need to develop in the Puppeteer repo.
+
+### Sandbox
+
+For easier development we provide a script to auto-generate the Angular project to test against. Simply run:
+
+```bash
+npm run sandbox -- --init
+```
+
+After that to run `@puppeteer/ng-schematics` against the Sandbox Angular project run:
+
+```bash
+npm run sandbox
+# or to auto-build and then run schematics
+npm run sandbox -- --build
+```
+
+To run the creating of single test schematic:
+
+```bash
+npm run sandbox:test
+```
+
+### Unit Testing
+
+The schematics utilize `@angular-devkit/schematics/testing` for verifying correct file creation and `package.json` updates. To execute the test suit:
+
+```bash
+npm run test
+```
