 You will now see the key pair in the hidden `.ssh` directory of your home as files `~/.ssh/id_ed25519` and `~/.ssh/id_ed25519.pub` (or `~/.ssh/id_rsa` and `~/.ssh/id_rsa.pub`).

 #### 2.2.2 Step 2: Transfer the public key
 Now the newly generated SSH public key needs to be transferred to your Ramses home directory. 
 To this end, we have set up a dedicated [Ramses key upload website](https://ramses-umc.itcc.uni-koeln.de/web-sshkey/login). Log in with your uniKIM credentials (username and password) and upload your public key. It will then be installed in your `~/.ssh/authorized_keys` file on Ramses and enable SSH authentication without a password request when used with your matching private key on the local host.
+In case key upload to the website is not possible, you can send it to us (hpc-mgr@uni-koeln.de) either as a file or by copy-paste of the public key file contents:
+`cat ~/.ssh/id_ed25519.pub`
