 
   These capabilities will override the default capabilities.
 
-  ```
+  ```elixir
   config :wallaby,
     selenium: [
       capabilities: %{
         # something
       }
+    ]
+  ```
+
+  ### Selenium Remote URL
+
+  It is possible to globally set Selenium's "Remote URL" by setting the following option.
+  
+  By default it is http://localhost:4444/wd/hub/
+
+  ```elixir
+  config :wallaby,
+    selenium: [
+      remote_url: "http://selenium_url"
     ]
   ```
 


  Start a Wallaby Session using this driver with the following command:

  ```
  {:ok, session} = Wallaby.start_session()
  ```



  ## Notes

  - Requires [selenium-server](https://www.seleniumhq.org/download/) to be running on port 4444. Wallaby does _not_ manage the start/stop of the Selenium server.
  - Requires [GeckoDriver](https://github.com/mozilla/geckodriver) to be installed in your path when using [Firefox](https://www.mozilla.org/en-US/firefox/new/). Firefox is used by default.
