+### Configuring access rights
+This is all done in `/home/ssh-port-forwarding/.ssh/authorized_keys`.
+
+First use the `ssh-keygen` command to create a private and public key pair on the client side. Don't type any password! Then use `cat ~/.ssh/id_rsa.pub` to display the content of your newly created public key. After that add a new line in the `authorized_keys` file on the server. Use the following line as an example. Your key starts at `AAAA...` and this all needs to be in a single line per key.
