+## Choose an issue
 
-## How to Contribute
+Playwright **requires an issue** for every contribution, except for minor documentation updates. We strongly recommend
+to pick an issue
+labeled [open-to-a-pull-request](https://github.com/microsoft/playwright/issues?q=is%3Aissue%20state%3Aopen%20label%3Aopen-to-a-pull-request)
+for your first contribution to the project.
 
-We strongly recommend that you open an issue before beginning any code modifications. This is particularly important if the changes involve complex logic or if the existing code isn't immediately clear. By doing so, we can discuss and agree upon the best approach to address a bug or implement a feature, ensuring that our efforts are aligned.
+If you are passionate about a bug/feature, but cannot find an issue describing it, **file an issue first**. This will
+facilitate the discussion, and you might get some early feedback from project maintainers before spending your time on
+creating a pull request.
 
-### Getting Code
-
-Make sure you're running Node.js 20 to verify and upgrade NPM do:
+## Make a change
 
+Make sure you're running Node.js 20 or later.
 ```bash
 node --version
-npm --version
-npm i -g npm@latest
 ```
 
-1. Clone this repository
-
-    ```bash
-    git clone https://github.com/microsoft/playwright
-    cd playwright
-    ```
-
-2. Install dependencies
-
-    ```bash
-    npm ci
-    ```
-
-3. Build Playwright
-
-    ```bash
-    npm run build
-    ```
-
-4. Run tests
-
-    This will run a test on line `23` in `page-fill.spec.ts`:
-
-    ```bash
-    npm run ctest -- page-fill:23
-    ```
-
-    See [here](#running--writing-tests) for more information about running and writing tests.
-
-### Code reviews
-
-All submissions, including submissions by project members, require review. We
-use GitHub pull requests for this purpose. Consult
-[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
-information on using pull requests.
-
-### Code Style
-
-- Coding style is fully defined in [.eslintrc](https://github.com/microsoft/playwright/blob/main/.eslintrc.js)
-- Comments should be generally avoided. If the code would not be understood without comments, consider re-writing the code to make it self-explanatory.
-
-To run code linter, use:
-
+Clone the repository. If you plan to send a pull request, it might be better to [fork the repository](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo) first.
 ```bash
-npm run eslint
+git clone https://github.com/microsoft/playwright
+cd playwright
 ```
 
-### API guidelines
+Install dependencies and run the build in watch mode.
+```bash
+npm ci
+npm run watch
+npx playwright install
+```
 
-When authoring new API methods, consider the following:
+**Experimental dev mode with Hot Module Replacement for recorder/trace-viewer/UI Mode**
 
-- Expose as little information as needed. When in doubt, don’t expose new information.
-- Methods are used in favor of getters/setters.
-  - The only exception is namespaces, e.g. `page.keyboard` and `page.coverage`
-- All string literals must be lowercase. This includes event names and option values.
-- Avoid adding "sugar" API (API that is trivially implementable in user-space) unless they're **very** common.
+```
+PW_HMR=1 npm run watch
+PW_HMR=1 npx playwright show-trace
+PW_HMR=1 npm run ctest -- --ui
+PW_HMR=1 npx playwright codegen
+PW_HMR=1 npx playwright show-report
+```
 
-### Commit Messages
+Playwright is a multi-package repository that uses npm workspaces. For browser APIs, look at [`packages/playwright-core`](https://github.com/microsoft/playwright/blob/main/packages/playwright-core). For test runner, see [`packages/playwright`](https://github.com/microsoft/playwright/blob/main/packages/playwright).
 
-Commit messages should follow the Semantic Commit Messages format:
+Note that some files are generated by the build, so the watch process might override your changes if done in the wrong file. For example, TypeScript types for the API are generated from the [`docs/src`](https://github.com/microsoft/playwright/blob/main/docs/src).
+
+Coding style is fully defined in [eslint.config.mjs](https://github.com/microsoft/playwright/blob/main/eslint.config.mjs). Before creating a pull request, or at any moment during development, run linter to check all kinds of things:
+  ```bash
+  npm run lint
+  ```
+
+Comments should have an explicit purpose and should improve readability rather than hinder it. If the code would not be understood without comments, consider re-writing the code to make it self-explanatory.
+
+### Write documentation
+
+Every part of the public API should be documented in [`docs/src`](https://github.com/microsoft/playwright/blob/main/docs/src), in the same change that adds/changes the API. We use markdown files with custom structure to specify the API. Take a look around for an example.
+
+Various other files are generated from the API specification. If you are running `npm run watch`, these will be re-generated automatically.
+
+Larger changes will require updates to the documentation guides as well. This will be made clear during the code review.
+
+## Add a test
+
+Playwright requires a test for almost any new or modified functionality. An exception would be a pure refactoring, but chances are you are doing more than that.
+
+There are multiple [test suites](https://github.com/microsoft/playwright/blob/main/tests) in Playwright that will be executed on the CI. The two most important that you need to run locally are:
+
+- Library tests cover APIs not related to the test runner.
+  ```bash
+  # fast path runs all tests in Chromium
+  npm run ctest
+
+  # slow path runs all tests in three browsers
+  npm run test
+  ```
+
+- Test runner tests.
+  ```bash
+  npm run ttest
+  ```
+
+Since Playwright tests are using Playwright under the hood, everything from our documentation applies, for example [this guide on running and debugging tests](https://playwright.dev/docs/running-tests#running-tests).
+
+Note that tests should be *hermetic*, and not depend on external services. Tests should work on all three platforms: macOS, Linux and Windows.
+

-### Writing Documentation
+## Send a pull request
 
-All API classes, methods, and events should have a description in [`docs/src`](https://github.com/microsoft/playwright/blob/main/docs/src). There's a [documentation linter](https://github.com/microsoft/playwright/tree/main/utils/doclint) which makes sure documentation is aligned with the codebase.
+All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose.
+Make sure to keep your PR (diff) small and readable. If necessary, split your contribution into multiple PRs.
+Consult [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more information on using pull requests.
 
-To run the documentation linter, use:
+After a successful code review, one of the maintainers will merge your pull request. Congratulations!
 
+## More details
+
+**No new dependencies**
+
+There is a very high bar for new dependencies, including updating to a new version of an existing dependency. We recommend to explicitly discuss this in an issue and get a green light from a maintainer, before creating a pull request that updates dependencies.
+
+**Custom browser build**
+
+To run tests with custom browser executable, specify `CRPATH`, `WKPATH` or `FFPATH` env variable that points to browser executable:
 ```bash
-npm run doc
+CRPATH=<path-to-executable> npm run ctest
 ```
 
-To build the documentation site locally and test how your changes will look in practice:
+You will also find `DEBUG=pw:browser` useful for debugging custom-builds.
 
-1. Clone the [microsoft/playwright.dev](https://github.com/microsoft/playwright.dev) repo
-1. Follow [the playwright.dev README instructions to "roll docs"](https://github.com/microsoft/playwright.dev/#roll-docs) against your local `playwright` repo with your changes in progress
-1. Follow [the playwright.dev README instructions to "run dev server"](https://github.com/microsoft/playwright.dev/#run-dev-server) to view your changes
+**Building documentation site**
 
-### Adding New Dependencies
+The [playwright.dev](https://playwright.dev/) documentation site lives in a separate repository, and documentation from [`docs/src`](https://github.com/microsoft/playwright/blob/main/docs/src) is frequently rolled there.
 
-For all dependencies (both installation and development):
-- **Do not add** a dependency if the desired functionality is easily implementable.
-- If adding a dependency, it should be well-maintained and trustworthy.
-
-A barrier for introducing new installation dependencies is especially high:
-- **Do not add** installation dependency unless it's critical to project success.
-
-### Running & Writing Tests
-
-- Every feature should be accompanied by a test.
-- Every public api event/method should be accompanied by a test.
-- Tests should be *hermetic*. Tests should not depend on external services.
-- Tests should work on all three platforms: Mac, Linux and Win. This is especially important for screenshot tests.
-
-Playwright tests are located in [`tests`](https://github.com/microsoft/playwright/blob/main/tests) and use `@playwright/test` test runner.
-These are integration tests, making sure public API methods and events work as expected.
-
-- To run all tests:
-
-    ```bash
-    npx playwright install
-    npm run test
-    ```
-
-    Be sure to run `npm run build` or let `npm run watch` run before you re-run the
-    tests after making your changes to check them.
-
-- To run tests in Chromium
-
-    ```bash
-    npm run ctest # also `ftest` for firefox and `wtest` for WebKit
-    npm run ctest -- page-fill:23 # runs line 23 of page-fill.spec.ts
-    ```
-
-- To run tests in WebKit / Firefox, use `wtest` or `ftest`.
-
-- To run the Playwright test runner tests
-
-    ```bash
-    npm run ttest
-    npm run ttest -- --grep "specific test"
-    ```
-
-- To run a specific test, substitute `it` with `it.only`, or use the `--grep 'My test'` CLI parameter:
-
-    ```js
-    ...
-    // Using "it.only" to run a specific test
-    it.only('should work', async ({server, page}) => {
-      const response = await page.goto(server.EMPTY_PAGE);
-      expect(response.ok).toBe(true);
-    });
-    // or
-    playwright test --config=xxx --grep 'should work'
-    ```
-
-- To disable a specific test, substitute `it` with `it.skip`:
-
-    ```js
-    ...
-    // Using "it.skip" to skip a specific test
-    it.skip('should work', async ({server, page}) => {
-      const response = await page.goto(server.EMPTY_PAGE);
-      expect(response.ok).toBe(true);
-    });
-    ```
-
-- To run tests in non-headless (headed) mode:
-
-    ```bash
-    npm run ctest -- --headed
-    ```
-
-- To run tests with custom browser executable, specify `CRPATH`, `WKPATH` or `FFPATH` env variable that points to browser executable:
-
-    ```bash
-    CRPATH=<path-to-executable> npm run ctest
-    ```
-
-- When should a test be marked with `skip` or `fixme`?
-
-  - **`skip(condition)`**: This test *should ***never*** work* for `condition`
-    where `condition` is usually something like: `test.skip(browserName === 'chromium', 'This does not work because of ...')`.
-
-  - **`fixme(condition)`**: This test *should ***eventually*** work* for `condition`
-    where `condition` is usually something like: `test.fixme(browserName === 'chromium', 'We are waiting for version x')`.
+Most of the time this should not concern you. However, if you are doing something unusual in the docs, you can build locally and test how your changes will look in practice:
+1. Clone the [microsoft/playwright.dev](https://github.com/microsoft/playwright.dev) repo.
+1. Follow [the playwright.dev README instructions to "roll docs"](https://github.com/microsoft/playwright.dev/#roll-docs) against your local `playwright` repo with your changes in progress.
+1. Follow [the playwright.dev README instructions to "run dev server"](https://github.com/microsoft/playwright.dev/#run-dev-server) to view your changes.

+# How to File a Bug Report That Actually Gets Resolved
+
+Make sure you’re on the latest Playwright release before filing. Check existing GitHub issues to avoid duplicates.
+
+## Use the Template
+
+Follow the **Bug Report** template. It guides you step-by-step:
+
+- Fill it out thoroughly.
+- Clearly list the steps needed to reproduce the bug.
+- Provide what you expected to see versus what happened in reality.
+- Include system info from `npx envinfo --preset playwright`.
+
+## Keep Your Repro Minimal
+
+We can't parse your entire code base. Reduce it down to the absolute essentials:
+
+- Start a fresh project (`npm init playwright@latest new-project`).
+- Add only the code/DOM needed to show the problem.
+- Only use major frameworks if necessary (React, Angular, static HTTP server, etc.). 
+- Avoid adding extra libraries unless absolutely necessary. Note that we won't install any suspect dependencies.
+
+## Why This Matters
+- Most issues that lack a repro turn out to be misconfigurations or usage errors.
+- We can't fix problems if we can’t reproduce them ourselves.
+- We can’t debug entire private projects or handle sensitive credentials.
+- Each confirmed bug will have a test in our repo, so your repro must be as clean as possible.
+
+## More Help
+
+- [Stack Overflow’s Minimal Reproducible Example Guide](https://stackoverflow.com/help/minimal-reproducible-example)
+- [Playwright Debugging Tools](https://playwright.dev/docs/debug)
+
+## Bottom Line
+A well-isolated bug speeds up verification and resolution. Minimal, public repro or it’s unlikely we can assist.

 Creates a locator matching all elements that match one or both of the two locators.

+Note that when both locators match something, the resulting locator will have multiple matches, potentially causing a [locator strictness](../locators.md#strictness) violation.
 
 **Usage**
 
 Consider a scenario where you'd like to click on a "New email" button, but sometimes a security settings dialog shows up instead. In this case, you can wait for either a "New email" button, or a dialog and act accordingly.
 
+:::note
+If both "New email" button and security dialog appear on screen, the "or" locator will match both of them,
+possibly throwing the ["strict mode violation" error](../locators.md#strictness). In this case, you can use [`method: Locator.first`] to only match one of them.

+## Assertion testing vs Snapshot testing
+
+Snapshot testing and assertion testing serve different purposes in test automation:
+
+### Assertion testing
+Assertion testing is a targeted approach where you assert specific values or conditions about elements or components. For instance, with Playwright, [`method: LocatorAssertions.toHaveText`]
+verifies that an element contains the expected text, and [`method: LocatorAssertions.toHaveValue`]
+confirms that an input field has the expected value.
+Assertion tests are specific and generally check the current state of an element or property
+against an expected, predefined state.
+They work well for predictable, single-value checks but are limited in scope when testing the
+broader structure or variations.
+
+**Advantages**
+- **Clarity**: The intent of the test is explicit and easy to understand.
+- **Specificity**: Tests focus on particular aspects of functionality, making them more robust
+  against unrelated changes.
+- **Debugging**: Failures provide targeted feedback, pointing directly to the problematic aspect.
+
+**Disadvantages**
+- **Verbose for complex outputs**: Writing assertions for complex data structures or large outputs
+  can be cumbersome and error-prone.
+- **Maintenance overhead**: As code evolves, manually updating assertions can be time-consuming.
+
+### Snapshot testing
+Snapshot testing captures a “snapshot” or representation of the entire
+state of an element, component, or data at a given moment, which is then saved for future
+comparisons. When re-running tests, the current state is compared to the snapshot, and if there
+are differences, the test fails. This approach is especially useful for complex or dynamic
+structures, where manually asserting each detail would be too time-consuming. Snapshot testing
+is broader and more holistic than assertion testing, allowing you to track more complex changes over time.
+
+**Advantages**
+- **Simplifies complex outputs**: For example, testing a UI component's rendered output can be tedious with traditional assertions. Snapshots capture the entire output for easy comparison.
+- **Quick Feedback loop**: Developers can easily spot unintended changes in the output.
+- **Encourages consistency**: Helps maintain consistent output as code evolves.
+
+**Disadvantages**
+- **Over-Reliance**: It can be tempting to accept changes to snapshots without fully understanding
+  them, potentially hiding bugs.
+- **Granularity**: Large snapshots may be hard to interpret when differences arise, especially
+  if minor changes affect large portions of the output.
+- **Suitability**: Not ideal for highly dynamic content where outputs change frequently or
+  unpredictably.
+
+### When to use
+
+- **Snapshot testing** is ideal for:
+  - UI testing of whole pages and components.
+  - Broad structural checks for complex UI components.
+  - Regression testing for outputs that rarely change structure.
+
+- **Assertion testing** is ideal for:
+  - Core logic validation.
+  - Computed value testing.
+  - Fine-grained tests requiring precise conditions.
+
+By combining snapshot testing for broad, structural checks and assertion testing for specific functionality, you can achieve a well-rounded testing strategy.
+
+## Aria snapshots
+
+In Playwright, aria snapshots provide a YAML representation of the accessibility tree of a page.
+These snapshots can be stored and compared later to verify if the page structure remains consistent or meets defined
+expectations.
+
+The YAML format describes the hierarchical structure of accessible elements on the page, detailing **roles**, **attributes**, **values**, and **text content**.
+The structure follows a tree-like syntax, where each node represents an accessible element, and indentation indicates
+nested elements.
+
+Each accessible element in the tree is represented as a YAML node:
+
+```yaml
+- role "name" [attribute=value]
+```
+
+- **role**: Specifies the ARIA or HTML role of the element (e.g., `heading`, `list`, `listitem`, `button`).
+- **"name"**: Accessible name of the element. Quoted strings indicate exact values, `/patterns/` are used for regular expression.
+- **[attribute=value]**: Attributes and values, in square brackets, represent specific ARIA attributes, such
+  as `checked`, `disabled`, `expanded`, `level`, `pressed`, or `selected`.
+
+These values are derived from ARIA attributes or calculated based on HTML semantics. To inspect the accessibility tree
+structure of a page, use the [Chrome DevTools Accessibility Tab](https://developer.chrome.com/docs/devtools/accessibility/reference#tab).
+
+
+## Snapshot matching
+
+The [`method: LocatorAssertions.toMatchAriaSnapshot`] assertion method in Playwright compares the accessible
+structure of the locator scope with a predefined aria snapshot template, helping validate the page's state against
+testing requirements.
+
+For the following DOM:
+
+```html
+<h1>title</h1>
+```
+
+You can match it using the following snapshot template:
+
+```js
+await expect(page.locator('body')).toMatchAriaSnapshot(`
+  - heading "title"
+`);
+```
+
+```python sync
+expect(page.locator("body")).to_match_aria_snapshot("""
+  - heading "title"
+""")
+```
+
+```python async
+await expect(page.locator("body")).to_match_aria_snapshot("""
+  - heading "title"
+""")
+```
+
+```java
+assertThat(page.locator("body")).matchesAriaSnapshot("""
+  - heading "title"
+""");
+```
+
+```csharp
+await Expect(page.Locator("body")).ToMatchAriaSnapshotAsync(@"
+  - heading ""title""
+");
+```
+
+When matching, the snapshot template is compared to the current accessibility tree of the page:
+
+* If the tree structure matches the template, the test passes; otherwise, it fails, indicating a mismatch between
+  expected and actual accessibility states.
+* The comparison is case-sensitive and collapses whitespace, so indentation and line breaks are ignored.
+* The comparison is order-sensitive, meaning the order of elements in the snapshot template must match the order in the
+  page's accessibility tree.
+
+
+### Partial matching
+
+You can perform partial matches on nodes by omitting attributes or accessible names, enabling verification of specific
+parts of the accessibility tree without requiring exact matches. This flexibility is helpful for dynamic or irrelevant
+attributes.
+
+```html
+<button>Submit</button>
+```
+
+*aria snapshot*
+
+```yaml
+- button
+```
+
+In this example, the button role is matched, but the accessible name ("Submit") is not specified, allowing the test to
+pass regardless of the button's label.
+
+<hr/>
+
+For elements with ARIA attributes like `checked` or `disabled`, omitting these attributes allows partial matching,
+focusing solely on role and hierarchy.
+
+```html
+<input type="checkbox" checked>
+```
+
+*aria snapshot for partial match*
+
+```yaml
+- checkbox
+```
+
+In this partial match, the `checked` attribute is ignored, so the test will pass regardless of the checkbox state.
+
+<hr/>
+
+Similarly, you can partially match children in lists or groups by omitting specific list items or nested elements.
+
+```html
+<ul>
+  <li>Feature A</li>
+  <li>Feature B</li>
+  <li>Feature C</li>
+</ul>
+```
+
+*aria snapshot for partial match*
+
+```yaml
+- list
+  - listitem: Feature B
+```
+
+Partial matches let you create flexible snapshot tests that verify essential page structure without enforcing
+specific content or attributes.
+
+### Strict matching
+
+By default, a template containing the subset of children will be matched:
+
+```html
+<ul>
+  <li>Feature A</li>
+  <li>Feature B</li>
+  <li>Feature C</li>
+</ul>
+```
+
+*aria snapshot for partial match*
+
+```yaml
+- list
+  - listitem: Feature B
+```
+
+
+The `/children` property can be used to control how child elements are matched:
+- `contain` (default): Matches if all specified children are present in order
+- `equal`: Matches if the children exactly match the specified list in order
+- `deep-equal`: Matches if the children exactly match the specified list in order, including nested children
+
+```html
+<ul>
+  <li>Feature A</li>
+  <li>Feature B</li>
+  <li>Feature C</li>
+</ul>
+```
+
+*aria snapshot will fail due to Feature C not being in the template*
+
+```yaml
+- list
+  - /children: equal
+  - listitem: Feature A
+  - listitem: Feature B
+```
+
+### Matching with regular expressions
+
+Regular expressions allow flexible matching for elements with dynamic or variable text. Accessible names and text can
+support regex patterns.
+
+```html
+<h1>Issues 12</h1>
+```
+
+*aria snapshot with regular expression*
+
+```yaml
+- heading /Issues \d+/
+```
+
+## Generating snapshots
+
+Creating aria snapshots in Playwright helps ensure and maintain your application's structure.
+You can generate snapshots in various ways depending on your testing setup and workflow.
+
+### Generating snapshots with the Playwright code generator
+
+If you're using Playwright's [Code Generator](./codegen.md), generating aria snapshots is streamlined with its
+interactive interface:
+
+- **"Assert snapshot" Action**: In the code generator, you can use the "Assert snapshot" action to automatically create
+a snapshot assertion for the selected elements. This is a quick way to capture the aria snapshot as part of your
+recorded test flow.
+
+- **"Aria snapshot" Tab**: The "Aria snapshot" tab within the code generator interface visually represents the
+aria snapshot for a selected locator, letting you explore, inspect, and verify element roles, attributes, and
+accessible names to aid snapshot creation and review.
+
+### Updating snapshots with `@playwright/test` and the `--update-snapshots` flag
+* langs: js
+
+When using the Playwright test runner (`@playwright/test`), you can automatically update snapshots with the `--update-snapshots` flag, `-u` for short.
+
+Running tests with the `--update-snapshots` flag will update snapshots that did not match. Matching snapshots will not be updated.
+
+```bash
+npx playwright test --update-snapshots
+```
+
+Updating snapshots is useful when application structure changes require new snapshots as a baseline. Note that Playwright will wait for the maximum expect timeout specified in the test runner configuration to ensure the page is settled before taking the snapshot. It might be necessary to adjust the `--timeout` if the test hits the timeout while generating snapshots.
+
+#### Empty template for snapshot generation
+
+Passing an empty string as the template in an assertion generates a snapshot on-the-fly:
+
+```js
+await expect(locator).toMatchAriaSnapshot('');
+```
+
+Note that Playwright will wait for the maximum expect timeout specified in the test runner configuration to ensure the
+page is settled before taking the snapshot. It might be necessary to adjust the `--timeout` if the test hits the timeout
+while generating snapshots.
+
+#### Snapshot patch files
+
+When updating snapshots, Playwright creates patch files that capture differences. These patch files can be reviewed,
+applied, and committed to source control, allowing teams to track structural changes over time and ensure updates are
+consistent with application requirements.
+
+The way source code is updated can be changed using the `--update-source-method` flag. There are several options available:
+
+- **"patch"** (default): Generates a unified diff file that can be applied to the source code using `git apply`.
+- **"3way"**: Generates merge conflict markers in your source code, allowing you to choose whether to accept changes.
+- **"overwrite"**: Overwrites the source code with the new snapshot values.
+
+```bash
+npx playwright test --update-snapshots --update-source-method=3way
+```
+
+#### Snapshots as separate files
+
+To store your snapshots in a separate file, use the `toMatchAriaSnapshot` method with the `name` option, specifying a `.aria.yml` file extension.
+
+```js
+await expect(page.getByRole('main')).toMatchAriaSnapshot({ name: 'main.aria.yml' });
+```
+
+By default, snapshots from a test file `example.spec.ts` are placed in the `example.spec.ts-snapshots` directory. As snapshots should be the same across browsers, only one snapshot is saved even if testing with multiple browsers. Should you wish, you can customize the [snapshot path template](./api/class-testconfig#test-config-snapshot-path-template) using the following configuration:
+
+```js
+export default defineConfig({
+  expect: {
+    toMatchAriaSnapshot: {
+      pathTemplate: '__snapshots__/{testFilePath}/{arg}{ext}',
+    },
+  },
+});
+```
+
+### Using the `Locator.ariaSnapshot` method
+
+The [`method: Locator.ariaSnapshot`] method allows you to programmatically create a YAML representation of accessible
+elements within a locator's scope, especially helpful for generating snapshots dynamically during test execution.
+
+**Example**:
+
+```js
+const snapshot = await page.locator('body').ariaSnapshot();
+console.log(snapshot);
+```
+
+```python sync
+snapshot = page.locator("body").aria_snapshot()
+print(snapshot)
+```
+
+```python async
+snapshot = await page.locator("body").aria_snapshot()
+print(snapshot)
+```
+
+```java
+String snapshot = page.locator("body").ariaSnapshot();
+System.out.println(snapshot);
+```
+
+```csharp
+var snapshot = await page.Locator("body").AriaSnapshotAsync();
+Console.WriteLine(snapshot);
+```
+
+This command outputs the aria snapshot within the specified locator's scope in YAML format, which you can validate
+or store as needed.
+
+## Accessibility tree examples
+
+### Headings with level attributes
+
+Headings can include a `level` attribute indicating their heading level.
+
+```html
+<h1>Title</h1>
+<h2>Subtitle</h2>
+```
+
+*aria snapshot*
+
+```yaml
+- heading "Title" [level=1]
+- heading "Subtitle" [level=2]
+```
+
+### Text nodes
+
+Standalone or descriptive text elements appear as text nodes.
+
+```html
+<div>Sample accessible name</div>
+```
+
+*aria snapshot*
+
+```yaml
+- text: Sample accessible name
+```
+
+### Inline multiline text
+
+Multiline text, such as paragraphs, is normalized in the aria snapshot.
+
+```html
+<p>Line 1<br>Line 2</p>
+```
+
+*aria snapshot*
+
+```yaml
+- paragraph: Line 1 Line 2
+```
+
+### Links
+
+Links display their text or composed content from pseudo-elements.
+
+```html
+<a href="#more-info">Read more about Accessibility</a>
+```
+
+*aria snapshot*
+
+```yaml
+- link "Read more about Accessibility"
+```
+
+### Text boxes
+
+Input elements of type `text` show their `value` attribute content.
+
+```html
+<input type="text" value="Enter your name">
+```
+
+*aria snapshot*
+
+```yaml
+- textbox: Enter your name
+```
+
+### Lists with items
+
+Ordered and unordered lists include their list items.
+
+```html
+<ul aria-label="Main Features">
+  <li>Feature 1</li>
+  <li>Feature 2</li>
+</ul>
+```
+
+*aria snapshot*
+
+```yaml
+- list "Main Features":
+  - listitem: Feature 1
+  - listitem: Feature 2
+```
+
+### Grouped elements
+
+Groups capture nested elements, such as `<details>` elements with summary content.
+
+```html
+<details>
+  <summary>Summary</summary>
+  <p>Detail content here</p>
+</details>
+```
+
+*aria snapshot*
+
+```yaml
+- group: Summary
+```
+
+### Attributes and states
+
+Commonly used ARIA attributes, like `checked`, `disabled`, `expanded`, `level`, `pressed`, and `selected`, represent
+control states.
+
+#### Checkbox with `checked` attribute
+
+```html
+<input type="checkbox" checked>
+```
+
+*aria snapshot*
+
+```yaml
+- checkbox [checked]
+```
+
+#### Button with `pressed` attribute

 ### Run tests on CI
 
 Setup CI/CD and run your tests frequently. The more often you run your tests the better. Ideally you should run your tests on each commit and pull request. Playwright comes with a [GitHub actions workflow](/ci-intro.md) so that tests will run on CI for you with no setup required. Playwright can also be setup on the [CI environment](/ci.md) of your choice.
 
 Use Linux when running your tests on CI as it is cheaper. Developers can use whatever environment when running locally but use linux on CI. Consider setting up [Sharding](./test-sharding.md) to make CI faster.
 
+
+#### Optimize browser downloads on CI
+
+Only install the browsers that you actually need, especially on CI. For example, if you're only testing with Chromium, install just Chromium.
+
+```bash title=".github/workflows/playwright.yml"
+# Instead of installing all browsers
+npx playwright install --with-deps
+
+# Install only Chromium
+npx playwright install chromium --with-deps
+```
+
+This saves both download time and disk space on your CI machines.
+
 ### Lint your tests
 
 We recommend TypeScript and linting with ESLint for your tests to catch errors early. Use [`@typescript-eslint/no-floating-promises`](https://typescript-eslint.io/rules/no-floating-promises/) [ESLint](https://eslint.org) rule to make sure there are no missing awaits before the asynchronous calls to the Playwright API. On your CI you can run `tsc --noEmit` to ensure that functions are called with the right signature.

 For Google Chrome, Microsoft Edge and other Chromium-based browsers, by default, Playwright uses open source Chromium builds. Since the Chromium project is ahead of the branded browsers, when the world is on Google Chrome N, Playwright already supports Chromium N+1 that will be released in Google Chrome and Microsoft Edge a few weeks later.
 
+### Chromium: headless shell
+
+Playwright ships a regular Chromium build for headed operations and a separate [chromium headless shell](https://developer.chrome.com/blog/chrome-headless-shell) for headless mode.
+
+If you are only running tests in headless shell (i.e. the `channel` option is **not** specified), for example on CI, you can avoid downloading the full Chromium browser by passing `--only-shell` during installation.
+
+```bash js
+# only running tests headlessly
+npx playwright install --with-deps --only-shell
+```
+
+```bash java
+# only running tests headlessly

+
+```bash csharp
+# only running tests headlessly
+pwsh bin/Debug/netX/playwright.ps1 install --with-deps --only-shell
+```
+
+### Chromium: new headless mode
+
+You can opt into the new headless mode by using `'chromium'` channel. As [official Chrome documentation puts it](https://developer.chrome.com/blog/chrome-headless-shell):
+
+> New Headless on the other hand is the real Chrome browser, and is thus more authentic, reliable, and offers more features. This makes it more suitable for high-accuracy end-to-end web app testing or browser extension testing.
+
+See [issue #33566](https://github.com/microsoft/playwright/issues/33566) for details.
+
+```js
+import { defineConfig, devices } from '@playwright/test';
+
+export default defineConfig({
+  projects: [
+    {
+      name: 'chromium',
+      use: { ...devices['Desktop Chrome'], channel: 'chromium' },

+  ],
+});

+  public static void main(String[] args) {
+    try (Playwright playwright = Playwright.create()) {
+      Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setChannel("chromium"));
+      Page page = browser.newPage();
+      // ...

+  }

 ### Google Chrome & Microsoft Edge
 
 While Playwright can download and use the recent Chromium build, it can operate against the branded Google Chrome and Microsoft Edge browsers available on the machine (note that Playwright doesn't install them by default). In particular, the current Playwright version will support Stable and Beta channels of these browsers.
 
-Available channels are `chrome`, `msedge`, `chrome-beta`, `msedge-beta` or `msedge-dev`.

+
+1. **Using [`--init`](https://docs.docker.com/reference/cli/docker/container/run/#init)** Docker flag is recommended to avoid special treatment for processes with PID=1. This is a common reason for zombie processes.
+

 ### Using on CI
 
 See our [Continuous Integration guides](./ci.md) for sample configs.
 
+### Remote Connection
+
+You can run Playwright Server in Docker while keeping your tests running on the host system or another machine. This is useful for running tests on unsupported Linux distributions or remote execution scenarios.
+
+#### Running the Playwright Server
+
+Start the Playwright Server in Docker:
+
+```bash
+docker run -p 3000:3000 --rm --init -it --workdir /home/pwuser --user pwuser mcr.microsoft.com/playwright:v%%VERSION%%-noble /bin/sh -c "npx -y playwright@%%VERSION%% run-server --port 3000 --host 0.0.0.0"
+```
+
+#### Connecting to the Server
+* langs: js
+
+There are two ways to connect to the remote Playwright server:
+
+1. Using environment variable with `@playwright/test`:
+
+```bash
+PW_TEST_CONNECT_WS_ENDPOINT=ws://127.0.0.1:3000/ npx playwright test
+```
+
+2. Using the [`method: BrowserType.connect`] API for other applications:
+
+```js
+const browser = await playwright['chromium'].connect('ws://127.0.0.1:3000/');
+```
+
+#### Connecting to the Server
+* langs: python, csharp, java
+
+```python sync
+from playwright.sync_api import sync_playwright
+
+with sync_playwright() as p:
+    browser = p.chromium.connect("ws://127.0.0.1:3000/")
+```
+
+```python async
+from playwright.async_api import async_playwright
+
+async with async_playwright() as p:
+    browser = await p.chromium.connect("ws://127.0.0.1:3000/")
+```
+
+```csharp
+using Microsoft.Playwright;
+
+using var playwright = await Playwright.CreateAsync();
+await using var browser = await playwright.Chromium.ConnectAsync("ws://127.0.0.1:3000/");
+```
+
+```java
+package org.example;
+
+import com.microsoft.playwright.*;
+import java.nio.file.Paths;
+
+public class App {
+  public static void main(String[] args) {
+    try (Playwright playwright = Playwright.create()) {
+      Browser browser = playwright.chromium().connect("ws://127.0.0.1:3000/");
+    }
+  }
+}
+```
+
+#### Network Configuration
+
+If you need to access local servers from within the Docker container:
+
+```bash
+docker run --add-host=hostmachine:host-gateway -p 3000:3000 --rm --init -it --workdir /home/pwuser --user pwuser mcr.microsoft.com/playwright:v%%VERSION%%-noble /bin/sh -c "npx -y playwright@%%VERSION%% run-server --port 3000 --host 0.0.0.0"
+```
+
+This makes `hostmachine` point to the host's localhost. Your tests should use `hostmachine` instead of `localhost` when accessing local servers.
+
+:::note
+When running tests remotely, ensure the Playwright version in your tests matches the version running in the Docker container.

 Global setup will re-run when you debug tests as this ensures an isolated environment and dedicated setup for the test.
