+sudo /srv/docker/bridgehead/bridgehead install <Project>
 ```
 
 Finally, you need to configure your sites secrets. These are places as configuration for each bridgeheads system unit. Refer to the section for your specific project:
 
-For Every Project you need to set the proxy this way, if you have a proxy.
