 #### Configure SSH access from the PHP container
 
-If you SSH access to the remote host is protected by a public/private key pair, then you have to configure you Docker container to be able to access the remote host. Here are the steps you need to take:
-
-```bash
-docker-compose exec php sh
-ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
-# For all the following questions just hit enter
-cat /root/.ssh/id_rsa.pub
-```
-
-This will show you the just created public key on the console and you should copy that output and then once go to your remote host and add that key to the end of the file `~/.ssh/authorized_keys`.
-
+Your host SSH configuration is automatically forwarded to the PHP docker container using sockets and you don't have to do anything to make it work, as long as your host is configured correctly to access your live site via SSH - in this case the PHP container can too.
