-Connecting to Browser
-~~~~~~~~~~~~~~~~~~~~~
-
-If you want to see the browser being automated for JavaScript or bok-choy tests,
-you can connect to the container running it via VNC.

-+------------------------+----------------------+
-| Browser                | VNC connection       |
-+========================+======================+
-| Firefox (Default)      | vnc://0.0.0.0:25900  |
-+------------------------+----------------------+
-| Chrome (via Selenium)  | vnc://0.0.0.0:15900  |
-+------------------------+----------------------+

-On macOS, enter the VNC connection string in the address bar in Safari to
-connect via VNC. The VNC passwords for both browsers are randomly generated and
-logged at container startup, and can be found by running ``make vnc-passwords``.
-
-Most tests are run in Firefox by default.  To use Chrome for tests that normally
-use Firefox instead, prefix the test command with
-``SELENIUM_BROWSER=chrome SELENIUM_HOST=edx.devstack.chrome``.
