+# 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.
+
+### Code of Conduct
+
+This project has adopted the [Microsoft Open Source Code of Conduct](https://opensource.microsoft.com/codeofconduct/).

+### User profile
 
-### Running headless browser (Browser without GUI).
+You can run Playwright MCP with persistent profile like a regular browser (default), in isolated contexts for testing sessions, or connect to your existing browser using the browser extension.
 
-This mode is useful for background or batch operations.
+**Persistent profile**
+
+All the logged in information will be stored in the persistent profile, you can delete it between sessions if you'd like to clear the offline state.
+Persistent profile is located at the following locations and you can override it with the `--user-data-dir` argument.
+
+```bash
+# Windows
+%USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-profile
+
+# macOS
+- ~/Library/Caches/ms-playwright/mcp-{channel}-profile
+
+# Linux
+- ~/.cache/ms-playwright/mcp-{channel}-profile
+```
+
+**Isolated**
+
+In the isolated mode, each session is started in the isolated profile. Every time you ask MCP to close the browser,
+the session is closed and all the storage state for this session is lost. You can provide initial storage state
+to the browser via the config's `contextOptions` or via the `--storage-state` argument. Learn more about the storage
+state [here](https://playwright.dev/docs/auth).

+## 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.
