 In order to run behat tests locally with the right support for browser
 and JS environments under Linux, you will need to:
 
-- Have Java installed (see notes below)
-- Download Selenium Standalone Server v3.*
-
-http://www.seleniumhq.org/download/
-
-And run it with the following command:
-
-```
-java -jar /my-dir/selenium-server-standalone-3.1.0.jar
-```
-
 - Download the Chrome driver, unzip and copy into /usr/bin
 
 Check the latest `chromedriver` version at [https://googlechromelabs.github.io/chrome-for-testing/](https://googlechromelabs.github.io/chrome-for-testing/) that matches your configuration (linux64 for Ubuntu), then adapt the following command to the latest version. Use a version that matches your version of the Chrome browser.
 
 ```
-cd /tmp && wget https://storage.googleapis.com/chrome-for-testing-public/143.0.7499.40/linux64/chromedriver-linux64.zip && unzip chromedriver_linux64.zip && sudo mv chromedriver /usr/local/bin

 ### Chamilo configuration

+- Edit the tests/behat/behat.yml file and update the base_url param with your own Chamilo local URL and make sure your machine understands it (e.g. add it to your /etc/hosts file).
 - The main platform language and the admin user's language must be English (`platform_language = 'en_US'` in the `settings` table and admin user profile)
 - Social network tool must be available (`allow_social_tool = 'true'` in the `settings` table)
 - Student can register to the system (`allow_registration = 'true'` in the `settings` table)
 - Teacher can register to the system (`allow_registration_as_teacher = 'true'` in the `settings` table)
 
+### Launch the chromedriver
+```
+chromedriver --port=4444
+```
+If you want to run the tests with a different base_url (see behat.yml), you will need to ask chromedriver to allow calls from remote IPs. This has serious security implications if the testing machine is exposed to the internet, so please be careful.
+```
+chromedriver --port=4444 --allowed-origins='*' --allowed-ips={your-ip-on-the-local-network}

-## Java versions
-
-Not all java versions will work. For Ubuntu, `sudo apt install openjdk-11-jdk openjdk-11-jre` should do, but OpenJDK 17 will not work, for example.
-If you have several versions installed, you can update the "active" version with `sudo update-java-alternatives -l` to see the possibilities, then `sudo update-java-alternatives -s java-1.11.0-openjdk-amd64` or something like that to set it. Beware this can have a big impact on other things you run with Java (like your IDE?) so maybe think about undoing this later on...
