+## Configuration
 
+You can specify a `jest-playwright.config.js` at the root of the project or define a custom path using `JEST_PLAYWRIGHT_CONFIG` environment variable. It should export a config object.
+
+- `launchBrowserApp` <[object]> [All Playwright launch options](https://github.com/microsoft/playwright/blob/master/docs/api.md#browsertypelaunchbrowserappoptions) can be specified in config. Since it is JavaScript, you can use all stuff you need, including environment.
+- `context` <[object]> [All Playwright context options](https://github.com/microsoft/playwright/blob/master/docs/api.md#browsernewcontextoptions) can be specified in config.
+- `browser` <[string]>. Define a [browser](https://github.com/microsoft/playwright/blob/master/docs/api.md#class-browsertype) to run tests into.
+  - `chromium` Each test runs Chromium.
+  - `firefox` Each test runs Firefox.
+  - `webkit` Each test runs Webkit.
+- `exitOnPageError` <[boolean]> Exits page on any global error message thrown. Defaults to `true`.
+
+## Browser type
+
+You can specify browser in multiple ways:
+
+- With `BROWSER` environment variable
+- With your `jest-playwright.config.js`
+
+If you don't pass any value it will be use `chromium` as default
 
 Use Playwright in your tests:
 ```json
 "test": "BROWSER=chromium jest"
