+
+## Installation
+
+Use pip to install Playwright in your Python project. See [system requirements](#system-requirements).
+
+```sh
+pip install playwright
+python -m playwright install
+```
+
+These commands download the Playwright package and install browser binaries for Chromium, Firefox and WebKit. To modify this behavior see [installation parameters](./installation.md).
+
+## Usage
+
+Once installed, you can `import` Playwright in a Python script, and launch any of the 3 browsers (`chromium`, `firefox` and `webkit`).
+
+```python
+from playwright import sync_playwright
+
+with sync_playwright() as p:
+    browser = p.chromium.launch()
+    page = browser.new_page()
+    # interact with UI elements, assert values
+    browser.close()
+```
+
+Playwright supports two variations of the API: synchronous are asynchronous. If your modern project uses
+[asyncio](https://docs.python.org/3/library/asyncio.html), you should use async API:
+
+```python
+from playwright import async_playwright
+
+with async_playwright() as p:
+    browser = await p.chromium.launch()
+    page = await browser.new_page()
+    # interact with UI elements, assert values
+    await browser.close()
+```
+
+## First script
+
+In our first script, we will navigate to `whatsmyuseragent.org` and take a screenshot in WebKit.
+
+```python
+from playwright import sync_playwright
+
+with sync_playwright() as p:
+    browser = p.webkit.launch()
+    page = await browser.new_page()
+    page.goto("http://whatsmyuseragent.org/")
+    page.screenshot(path="example.png")
+    browser.close()
+```
+
+By default, Playwright runs the browsers in headless mode. To see the browser UI, pass the `headless=False` flag while launching the browser. You can also use `slowMo` to slow down execution. Learn more in the debugging tools [section](./debug.md).
+
+```python
+firefox.launch(headless=False, slowMo=50)
+```
+
+## Record scripts
+
+Command Line Interface [CLI](./cli.md) can be used to record user interactions and generate Python code.
+
+```sh
+python -m playwright codegen wikipedia.org
+```
+
+## System requirements
+
+Playwright requires Python version 3.7 or above. The browser binaries for Chromium,
+Firefox and WebKit work across the 3 platforms (Windows, macOS, Linux):
+
+* **Windows**: Works with Windows and Windows Subsystem for Linux (WSL).
+* **macOS**: Requires 10.14 or above.
+* **Linux**: Depending on your Linux distribution, you might need to install additional
+  dependencies to run the browsers.
+  * Firefox requires Ubuntu 18.04+
+  * For Ubuntu 18.04, the additional dependencies are defined in [our Docker image](https://github.com/microsoft/playwright/blob/master/utils/docker/Dockerfile.bionic),
+    which is based on Ubuntu.

+
+You can use our [Pytest integration](https://github.com/microsoft/playwright-pytest) to write end-to-end tests
+in Python.
+
+<!-- TOC -->
+
+## Usage
+
+```sh
+pip install pytest-playwright
+```
+
+Use the `page` fixture to write a basic test. See [more examples](#examples).
+
+```py
+def test_example_is_working(page):
+    page.goto("https://example.com")
+    assert page.innerText('h1') == 'Example Domain'
+    page.click("text=More information")
+```
+
+To run your tests, use pytest CLI.
+
+```sh
+# Run tests (Chromium and headless by default)
+pytest
+
+# Run tests in headful mode
+pytest --headful
+
+# Run tests in a different browser (chromium, firefox, webkit)
+pytest --browser firefox
+
+# Run tests in multiple browsers
+pytest --browser chromium --browser webkit
+```
+
+If you want to add the CLI arguments automatically without specifying them, you can use the [pytest.ini](https://docs.pytest.org/en/stable/reference.html#ini-options-ref) file:
+
+```ini
+# content of pytest.ini
+[pytest]
+# Run firefox with UI
+addopts = --headful --browser firefox
+
+```
+
+## Fixtures
+
+This plugin configures Playwright-specific [fixtures for pytest](https://docs.pytest.org/en/latest/fixture.html). To use these fixtures, use the fixture name as an argument to the test function.
+
+```py
+def test_my_app_is_working(fixture_name):
+    # Test using fixture_name
+    # ...
+```
+
+**Function scope**: These fixtures are created when requested in a test function and destroyed when the test ends.
+
+- `context`: New [browser context](https://playwright.dev/#path=docs%2Fcore-concepts.md&q=browser-contexts) for a test.
+- `page`: New [browser page](https://playwright.dev/#path=docs%2Fcore-concepts.md&q=pages-and-frames) for a test.
+
+**Session scope**: These fixtures are created when requested in a test function and destroyed when all tests end.
+
+- `browser`: Browser instance launched by Playwright.
+- `browser_name`: Browser name as string.
+- `is_chromium`, `is_webkit`, `is_firefox`: Booleans for the respective browser types.
+
+**Customizing fixture options**: For `browser` and `context` fixtures, use the the following fixtures to define custom launch options.
+
+- `browser_type_launch_args`: Override launch arguments for [`browserType.launch()`](https://playwright.dev/#path=docs%2Fapi.md&q=browsertypelaunchoptions). It should return a Dict.
+- `browser_context_args`: Override the options for [`browser.newContext()`](https://playwright.dev/#path=docs%2Fapi.md&q=browsernewcontextoptions). It should return a Dict.
+
+## Examples
+
+### Configure Mypy typings for auto-completion
+
+```py
+from playwright.sync_api import Page
+
+def test_visit_admin_dashboard(page: Page):
+    page.goto("/admin")
+    # ...
+```
+
+### Skip test by browser
+
+```py
+import pytest
+
+@pytest.mark.skip_browser("firefox")
+def test_visit_example(page):
+    page.goto("https://example.com")
+    # ...
+```
+
+### Run on a specific browser
+
+```py
+import pytest
+
+@pytest.mark.only_browser("chromium")
+def test_visit_example(page):
+    page.goto("https://example.com")
+    # ...
+```
+
+### Configure base-url
+
+Start Pytest with the `base-url` argument.
+
+```sh
+pytest --base-url http://localhost:8080
+```
+
+```py
+def test_visit_example(page):
+    page.goto("/admin")
+    # -> Will result in http://localhost:8080/admin
+```
+
+### Ignore HTTPS errors
+
+conftest.py
+
+```py
+import pytest
+
+@pytest.fixture(scope="session")
+def browser_context_args(browser_context_args):
+    return {
+        **browser_context_args,
+        "ignoreHTTPSErrors": True
+    }
+```
+
+### Use custom viewport size
+
+conftest.py
+
+```py
+import pytest
+
+@pytest.fixture(scope="session")
+def browser_context_args(browser_context_args):
+    return {
+        **browser_context_args,
+        "viewport": {
+            "width": 1920,
+            "height": 1080,
+        }
+    }
+```
+
+### Device emulation
+
+conftest.py
+
+```py
+import pytest
+
+@pytest.fixture(scope="session")
+def browser_context_args(browser_context_args, playwright):
+    iphone_11 = playwright.devices['iPhone 11 Pro']
+    return {
+        **browser_context_args,
+        **iphone_11,
+    }
+```
+
+## Debugging
+
+### Use with pdb
+
+Use the `breakpoint()` statement in your test code to pause execution and get a [pdb](https://docs.python.org/3/library/pdb.html) REPL.
+
+```py
+def test_bing_is_working(page):
+    page.goto("https://bing.com")
+    breakpoint()
+    # ...
+```
+
+### Screenshot on test failure
+
+You can capture screenshots for failed tests with a [pytest runtest hook](https://docs.pytest.org/en/6.1.0/reference.html?highlight=pytest_runtest_makereport#test-running-runtest-hooks). Add this to your `conftest.py` file.
+
+Note that this snippet uses `slugify` to convert test names to file paths, which can be installed with `pip install python-slugify`.
+
+```py
+# In conftest.py
+from slugify import slugify
+from pathlib import Path
+
+def pytest_runtest_makereport(item, call) -> None:
+    if call.when == "call":
+        if call.excinfo is not None and "page" in item.funcargs:
+            page = item.funcargs["page"]
+            screenshot_dir = Path(".playwright-screenshots")
+            screenshot_dir.mkdir(exist_ok=True)
+            page.screenshot(path=str(screenshot_dir / f"{slugify(item.nodeid)}.png"))
+```
+
+## Deploy to CI
+
+Use the [Playwright GitHub Action](https://github.com/microsoft/playwright-github-action) or [guides for other CI providers](https://playwright.dev/#path=docs%2Fci.md&q=) to deploy your tests to CI/CD
