-### Install
+### Installing Panther
 
 Use [Composer](https://getcomposer.org/) to install Panther in your project. You may want to use the `--dev` flag if you want to use Panther for testing only and not for web scraping in a production environment:
 
     composer req symfony/panther
 
     composer req --dev symfony/panther
 
-**Warning:** On \*nix systems, the `unzip` command must be installed or you will encounter an error similar to `RuntimeException: sh: 1: exec: /app/vendor/symfony/panther/src/ProcessManager/../../chromedriver-bin/chromedriver_linux64: Permission denied` (or `chromedriver_linux64: not found`).
+**Warning:** On \*nix systems, the `unzip` command must be installed, or you will encounter an error similar to `RuntimeException: sh: 1: exec: /app/vendor/symfony/panther/src/ProcessManager/../../chromedriver-bin/chromedriver_linux64: Permission denied` (or `chromedriver_linux64: not found`).
 The underlying reason is that PHP's `ZipArchive` doesn't preserve UNIX executable permissions.
 
+### Installing ChromeDriver and geckodriver
+
+Panther uses the WebDriver protocol to control the browser used to crawl websites.
+
+On all systems, you can use `dbrekelmans/browser-driver-installer` to install ChromeDriver and geckodriver locally:
+
+    composer require --dev dbrekelmans/bdi
+    vendor/bin/bdi detect drivers
+
+Panther will detect and use automatically drivers stored in the `drivers/` directory.
+
+Alternatively, you can use the package manager of your operating system to install them.
+
+On Ubuntu, run:
+
+    apt-get install chromium-chromedriver firefox-geckodriver
+
+On Mac, using [Homebrew](https://brew.sh):
+
+    brew install chromedriver geckodriver
+
+On Windows, using [chocolatey](https://chocolatey.org):
+
+    choco install chromedriver selenium-gecko-driver
+
+Finally, you can download manually [ChromeDriver](https://sites.google.com/a/chromium.org/chromedriver/) (for Chromium or Chrome)
+and [GeckoDriver](https://github.com/mozilla/geckodriver) (for Firefox) and put them anywhere in your `PATH`
+or in the `drivers/` directory of your project.

 #### Registering the PHPUnit Extension
 
-If you intend to use Panther to test your application, we strongly recommended to register the Panther PHPUnit extension.
