 FIREFOX_VERSION should either be `nimbus-firefox-release` or `nimbus-firefox-beta`. If you want to run your tests against nightly, please set the variable `UPDATE_FIREFOX_VERSION` to `true` and include it in the make command.
 
-#### make FIREFOX_VERSION integration_vnc_up

-First start a prod instance of Experimenter with:
-
-```bash
-make refresh&&make up_prod_detached
-```
-
-Then start the VNC service:
-
-```bash
-make FIREFOX_VERSION integration_vnc_up
-```
-
-Then open your VNC client (Safari does this on OSX or just use [VNC Viewer](https://www.realvnc.com/en/connect/download/viewer/)) and open `vnc://localhost:5900` with password `secret`. Right click on the desktop and select `Applications > Shell > Bash` and enter:
-
-```bash
-cd experimenter
-sudo apt get update
-sudo apt install tox
-chmod a+rwx tests/integration/.tox
-tox -c tests/integration/ -e integration-test-nimbus
-```
-
-This should run the integration tests and watch them run in a Firefox instance you can watch and interact with.
-
-To use NoVNC, navgate to this url `http://localhost:7902` with the password `secret`. Then you can follow the same steps as above.
