+# Contributing
+
+## Choose an issue
+
+Playwright MCP **requires an issue** for every contribution, except for minor documentation updates.
+
+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.
+
+## Make a change
+
+> [!WARNING]
+> The core of the Playwright MCP was moved to the [Playwright monorepo](https://github.com/microsoft/playwright).
+
+Clone the Playwright 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
+git clone https://github.com/microsoft/playwright
+cd playwright
+```
+
+Install dependencies and run the build in watch mode.
+```bash
+# install deps and run watch
+npm ci
+npm run watch
+npx playwright install
+```
+
+Source code for Playwright MCP is located at [packages/playwright/src/mcp](https://github.com/microsoft/playwright/blob/main/packages/playwright/src/mcp).
+
+```bash
+# list source files
+ls -la packages/playwright/src/mcp
+```
+
+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
+# lint the source base before sending PR
+npm run flint
+```
+
+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.
+
+## Add a test
+
+Playwright requires a test for the 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. Tests for Playwright MCP are located at [tests/mcp](https://github.com/microsoft/playwright/blob/main/tests/mcp).
+
+```bash
+# list test files
+ls -la tests/mcp
+```
+
+To run the mcp tests, use
+
+```bash
+# fast path runs all MCP tests in Chromium
+npm run mcp-ctest
+```
+
+```bash
+# slow path runs all tests in three browsers
+npm run mcp-test
+```
+
+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.
+
+## Write a commit message
+
+Commit messages should follow the [Semantic Commit Messages](https://www.conventionalcommits.org/en/v1.0.0/) format:
+
+```
+label(namespace): title
+
+description
+
+footer
+```
+
+1. *label* is one of the following:
+    - `fix` - bug fixes
+    - `feat` - new features
+    - `docs` - documentation-only changes
+    - `test` - test-only changes
+    - `devops` - changes to the CI or build
+    - `chore` - everything that doesn't fall under previous categories
+2. *namespace* is put in parentheses after label and is optional. Must be lowercase.
+3. *title* is a brief summary of changes.
+4. *description* is **optional**, new-line separated from title and is in present tense.
+5. *footer* is **optional**, new-line separated from *description* and contains "fixes" / "references" attribution to GitHub issues.
+
+Example:
+
+```
+feat(trace viewer): network panel filtering
+
+This patch adds a filtering toolbar to the network panel.
+<link to a screenshot>
+
+Fixes #123, references #234.
+```
+
+## Send a pull request
+
+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.
+
+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.
+
+## Contributor License Agreement
+
+This project welcomes contributions and suggestions.  Most contributions require you to agree to a
+Contributor License Agreement (CLA) declaring that you have the right to, and actually do, grant us
+the rights to use your contribution. For details, visit https://cla.opensource.microsoft.com.
+
+When you submit a pull request, a CLA bot will automatically determine whether you need to provide
+a CLA and decorate the PR appropriately (e.g., status check, comment). Simply follow the instructions
+provided by the bot. You will only need to do this once across all repos using our CLA.

+**Browser Extension**
+
+The Playwright MCP Chrome Extension allows you to connect to existing browser tabs and leverage your logged-in sessions and browser state. See [extension/README.md](extension/README.md) for installation and setup instructions.
+
+### Initial state
+
+There are multiple ways to provide the initial state to the browser context or a page.
+
+For the storage state, you can either:
+- Start with a user data directory using the `--user-data-dir` argument. This will persist all browser data between the sessions.
+- Start with a storage state file using the `--storage-state` argument. This will load cookies and local storage from the file into an isolated browser context.
+
+For the page state, you can use:
+
+- `--init-page` to point to a TypeScript file that will be evaluated on the Playwright page object. This allows you to run arbitrary code to set up the page.
+
+```ts
+// init-page.ts
+export default async ({ page }) => {
+  await page.context().grantPermissions(['geolocation']);
+  await page.context().setGeolocation({ latitude: 37.7749, longitude: -122.4194 });
+  await page.setViewportSize({ width: 1280, height: 720 });
+};
+```
+
+- `--init-script` to point to a JavaScript file that will be added as an initialization script. The script will be evaluated in every page before any of the page's scripts.
+This is useful for overriding browser APIs or setting up the environment.
+
+```js
+// init-script.js
+window.isPlaywrightMCP = true;
+```

+# Playwright MCP Chrome Extension
+
+## Introduction
+
+The Playwright MCP Chrome Extension allows you to connect to pages in your existing browser and leverage the state of your default user profile. This means the AI assistant can interact with websites where you're already logged in, using your existing cookies, sessions, and browser state, providing a seamless experience without requiring separate authentication or setup.
+
+## Prerequisites
+
+- Chrome/Edge/Chromium browser
+
+## Installation Steps
+
+### Download the Extension
+
+Download the latest Chrome extension from GitHub:
+- **Download link**: https://github.com/microsoft/playwright-mcp/releases
+
+### Load Chrome Extension
+
+1. Open Chrome and navigate to `chrome://extensions/`
+2. Enable "Developer mode" (toggle in the top right corner)
+3. Click "Load unpacked" and select the extension directory
+
+### Configure Playwright MCP server
+
+Configure Playwright MCP server to connect to the browser using the extension by passing the `--extension` option when running the MCP server:
+
+```json
+{
+  "mcpServers": {
+    "playwright-extension": {
+      "command": "npx",
+      "args": [
+        "@playwright/mcp@latest",
+        "--extension"
+      ]
+    }
+  }
+}
+```
+
+## Usage
+
+### Browser Tab Selection
+
+When the LLM interacts with the browser for the first time, it will load a page where you can select which browser tab the LLM will connect to. This allows you to control which specific page the AI assistant will interact with during the session.
+
+### Bypassing the Connection Approval Dialog
+
+By default, you'll need to approve each connection when the MCP server tries to connect to your browser. To bypass this approval dialog and allow automatic connections, you can use an authentication token.
+
+#### Using Your Unique Authentication Token
+
+1. After installing the extension, click on the extension icon or navigate to the extension's status page
+2. Copy the `PLAYWRIGHT_MCP_EXTENSION_TOKEN` value displayed in the extension UI
+3. Add it to your MCP server configuration:
+
+```json
+{
+  "mcpServers": {
+    "playwright-extension": {
+      "command": "npx",
+      "args": [
+        "@playwright/mcp@latest",
+        "--extension"
+      ],
+      "env": {
+        "PLAYWRIGHT_MCP_EXTENSION_TOKEN": "your-token-here"
+      }
+    }
+  }
+}
+```
+
+This token is unique to your browser profile and provides secure authentication between the MCP server and the extension. Once configured, you won't need to manually approve connections each time.
