+### SSH Access
+
+SSH access to the QEMU virtual machine can be enabled by using the `--ssh` flag. This will portforward `TCP2222` on the host machine to `TCP22` on the QEMU guest machine. This does not install or start an SSH server within the guest itself, so you will stil need to enable this on a per-guest basis. For Ubuntu guests, you can enable this by installing `openssh-server`.
+
+If the default port overlaps with another service on your host, you can override this with `--ssh-port $PORT`. This will still forward to port `TCP22` on the guest machine.
+
+Example of usage: -
+
+```
+$ ./quickemu.sh --vm mate.conf --ssh --ssh-port 1111
