+В Testplane добавлена возможность автоматической загрузки браузеров и драйверов для последующего локального запуска.
+
+<!-- truncate -->
+
+Раньше Testplane с протоколом автоматизации webdriver можно было запустить локально только с вручную запущенным [selenium-standalone](https://github.com/webdriverio/selenium-standalone). Теперь достаточно указать указать `gridUrl: "local"` в [Конфиге Testplane](/docs/v8/command-line) или запустить тесты с [CLI-опцией](/docs/v8/command-line) `--local`. В таком случае перед запуском тестов при необходимости будут загружены соответствующие браузеры и вебдрайверы к ним, которые также будут запущены для дальнейшего использования в этих тестах.
+
+Загрузить браузеры и вебдрайверы к ним можно и отдельно, с помощью команды [install-deps](/docs/v8/command-line#install-deps).
+
+Пример запуска тестов на локальном браузере с webdriver протоколом автоматизации:
+
+<video src={localBrowsersExampleUrl} width="100%" controls="controls" autoplay="autoplay">
+    Тег video не поддерживается вашим браузером.

+# How to Run Testplane in a Local Browser
+
+## Introduction
+
+Testplane can automatically download browsers in accordance with your [Testplane Config](/docs/v8/config/main).
+
+Additionally, if Testplane is used on a supported version of Ubuntu, the necessary deb packages for running browsers will also be downloaded in a similar manner.
+
+Running tests on a local browser can help with troubleshooting a problem that occurs when running on a remote grid, but using local browsers for screenshot testing is not recommended, as screenshots will vary depending on the operating system version.
+
+## Installing dependencies
+
+In a project with Testplane, you can execute the command `npx testplane install-deps`. This command will download the necessary browsers (`chrome` and `firefox`) and their web drivers (`chrome`, `firefox`, and `edge`).
+
+You can also download only the necessary browsers described in the config. For example, if the browser `chrome-dark` is described, you can download only this one with the command `npm testplane install-deps chrome-dark'.
+
+You can read more about this command on the respective page: [install-deps](/docs/v8/command-line#install-deps)
+
+## Running tests
+
+You can run tests on local browsers using the [CLI option](/docs/v8/command-line) `--local`, or with [gridUrl](/docs/v8/config/browsers/#grid_url): "local" in the [Testplane config](/docs/v8/config/main). For example:
+
+```bash
+npx testplane --local
+```
+
+This way, the corresponding web driver processes for supported browsers will be automatically started, and Testplane will use these locally launched drivers with locally downloaded browsers.
+
+If necessary, browsers will be downloaded before the test run, so running the `install-deps` command separately is not mandatory, especially if you want to quickly run a test in just one browser.
+
+## Debugging tests
+
+When `debug` is enabled in the config, web driver logs with a prefix will be output to stdout/stderr:
+
+```typescript
+export default {
+    // ... other Testplane settings
+    system: {
+        debug: true,
+    },
+};
+```
+
+To reduce excessive `webdriverio` logs, you can set the desired level for the `WDIO_LOG_LEVEL` environment variable.
+
+For example, here's how a launch would look with debugging enabled via an environment variable, `webdriverio` logging level set to `error` in a local browser with browserId `chrome` in the config:
+
+```bash
+testplane_system_debug=true WDIO_LOG_LEVEL=error npx testplane --local -b chrome
+```
+
+And the web driver logs will look something like this:
+
+```plaintext
+$ testplane_system_debug=true WDIO_LOG_LEVEL=error npx testplane --local -b chrome
+[chromedriver@130] Starting ChromeDriver 130.0.6723.116 (6ac35f94ae3d01152cf1946c896b0678e48f8ec4-refs/branch-heads/6723@{#1764}) on port 43415
+[chromedriver@130] Only local connections are allowed.
+[chromedriver@130] Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
+[chromedriver@130] ChromeDriver was started successfully on port 43415.
+```
+
+## Browser support {#browser-support}
+
+Here is the table of supported browsers:
+
+| Browser | Auto download | Auto driver download | Running webdriver |
+| ------- | ------------- | -------------------- | ----------------- |
+| Chrome  | +             | +                    | +                 |
+| Firefox | +             | +                    | +                 |
+| Edge    | -             | +                    | +                 |
+| Safari  | -             | +                    | +                 |
+
+Supported browser versions per OS:
+
+|   OS    | Windows | MacOs | Ubuntu 20 | Ubuntu 22 | Ubuntu 24 |
+| :-----: | ------- | ----- | --------- | --------- | --------- |
+| Chrome  | 73+     | 73+   | 73+       | 73+       | 73+       |
+| Firefox | 60+     | 60+   | 60+       | 91+       | 126+      |
+|  Edge   | \*      | \*    | \*        | \*        | \*        |

+
+-   -   Browser auto download is not supported, but if the browser is installed by the user himself, installed version will be used by Testplane.
+
+For virtual environments, you would need to run headless. "--no-sandbox" CLI arg for "chrome" browser could also be necessary:
+
+```typescript
+{
+    // other chrome browser settings
+    headless: true,
+    desiredCapabilities: {
+        browserName: "chrome",
+        browserVersion: "130.0",
+        "goog:chromeOptions": { args: ["--no-sandbox"] }
+    }
+}
+```

+Testplane is now able to automatically download browsers for running tests locally. Enjoy a hassle-free start with `--local` option if you don't need remote browser grid.

+<!-- truncate -->
+
+Previously, Testplane with the webdriver automation protocol could only be launched locally with a manually started [selenium-standalone](https://github.com/webdriverio/selenium-standalone). Now, it is enough to specify `gridUrl: "local"` in the [Testplane Config](/docs/v8/config/main) or run tests with the [CLI option](/docs/v8/command-line) `--local`. In this case, if necessary, the corresponding browsers and web drivers will be downloaded before running the tests, and they will also be launched for further use in these tests.
+
+You can also download the browsers and their web drivers separately using the [install-deps](/docs/v8/command-line#install-deps) command.
